My IP Address Is Linked To Another's Nameserver
Jul 27, 2007
Someone has registered a nameserver for their domain, using an IP address that is registered to a server that I lease at LiquidWeb. I'm not sure how this could affect me, since the nameserver doesn't really exist, but I assume that lookup requests could add significant traffic.
In any event, the registrant has not responded to email sent to the address listed in their domain records, and the registrar for the domain (Enom) indicates that they cannot help. Can anyone suggest the next step to get this domain holder to remove the record that includes my IP address? Is it necessary to begin sending certified postal mail?

My new host give me 1 ip to register for both (ns1 & ns2) nameserver. Is that correct?
Ex-host always gave me 2 ip's.

So we just got our VPS. The host has only given us 1 IP for running our own DNS. They provided a 2nd nameserver + IP to use at the registrar level but since this name server does not match or domain name, the registrar obviously cannot let us register this. Is there an issue if we set ns1 to our IP and ns2 like so even though the 2nd name server is not registered at the registrar level?
For instance:
ns1.ourdomain.com (our IP)
ns2.somedomainthehostprovided.com (which cannot be registered at the registrar level)

1) I use DNSMadeEasy for a couple of my important domains so I can utilize their failover service.
2) I use my own nameservers for everyone else.
At my register (GoDaddy) I've added host entries to my domain (let's call it host.com) for ALL of my nameservers: DNSMadeEasy and mine. For example here are my host entries:
1) nsdme0.host.com = 55.55.55.55 (DNSMadeEasy)
2) nsdme1.host.com = 56.55.55.55 (DNSMadeEasy)
3) nsdme2.host.com = 57.55.55.55 (DNSMadeEasy)
4) nsdme3.host.com = 58.55.55.55 (DNSMadeEasy)
5) nsdme4.host.com = 59.55.55.55 (DNSMadeEasy)
6) ns1.host.com = 60.55.55.55 (mine)
7) ns2.host.com = 61.55.55.55 (mine)
At the register I've then configured host.com to use the first five nameservers for itself, the DNSMadeEasy nameservers.
For less critical sites that I host I simply point them to ns1.host.com and ns2.host.com, my nameservers.
Now, here's the twist. If I use dig to look up www.host.com I get:
[root@lax1 ~]# dig +trace www.host.com
; <<>> DiG 9.3.3rc2 <<>> +trace www.host.com

BUT, if I lookup the nameserver (ns1.host.com) I get:

What I've realized is that the actual IP addresses for nameserver host entries come from a higher level server than my own, in this case H.GTLD-SERVERS.net. I guess this makes sense but I just hadn't realized it before. It looks like I don't even need to have record entries in my DNS records for the host nameservers.
Now for the question. Can I:
1) Remove my custom host nameserver entries from my register.
2) Add entries in my DNSMadeEasy records to specify the location of ns1.host.com and ns2.host.com.
3) Use the failover provided by DNSMadeEasy to also fail-over my DNS entries for my nameservers?
I know this would require one more hop if it works but it would allow me to provide failover ability to fifty domains without having to purchase the extra domains at DNSMadeEasy.

My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively.
- the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11
- the external ip addresses resolve to the above internal addresses
- the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
Code:
<VirtualHost 192.168.10.10:80>
...
ProxyPass /app http://app_server1:7777/app
ProxyPassReverse /app http://app_server1:7777/app
RewriteRule ^/$ /app/app1 [R,L]
...
<VirtualHost>
and
Code:
<VirtualHost 192.168.10.11:80>
...
ProxyPass /app http://app_server2:7777/app
ProxyPassReverse /app http://app_server2:7777/app
RewriteRule ^/$ /app/app2 [R,L]
...
<VirtualHost>
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?

I am using virtuozzo firewall to secure access.
I enter 58.27.175.211/255.255.255.0 for Source Address and Netmask for port 22.
But still I can connect using 58.181.103.217 or 58.27.151.120.
Second is it possible to enter two different ip address in source address?

I just bought a new ip address and want to setup this new ip as my server's main ip, making the 'existing main ip' as the secondary ip.
Which means, this new ip will be the server's default ip address for all services, including when connecting to other server.
I'm using CentOs 4.5 and swsoft's panels: HSPcomplete & Virtuozzo Power Panel, and Webmin.

I want to redirect a website to a particular URL so that the address bar shows the same URL and not the destination URL. I know it is possible via URL masking, however, I want it in such a way that whenever somebody clicks on any link in the website, the address bar should still show the original URL. To put it in simple words, Suppose I want to redirect [url] to [url]. Now if there is a link named contact/index.htm and somebody clicks on it the address bar should display [url]and not redirect to [url]
How can it be possible using URL Rewrite method in .htaccess file?

The problem usually goes like this:
- I can't access the webserver
- I'll try to restart httpd, and I'll get
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:443
To fix this, I run
[root@www1 ~]# lsof -i tcp:443
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
perl 11307 apache 4u IPv6 476943447 TCP *:https (LISTEN)
There is always leftover process that is causing the restart to fail. Once i force kill the process, I am able to restart httpd properly.
Now it is ok if this just occurs once in a while, but this problem keeps repeating itself almost everyday at 4am server time (cron time?). What can I do to permanently fix this?

I have a domain hosted at godaddy.com and I decided to go with VPS hosting elsewhere. I have changed the nameservers to [url]and [url]at godaddy. I set up the reseller account in WHM but the nameservers point to something other than [url]I am trying to change them to the correct nameservers by using the "Nameserver IP Assigment" tool but it is taking literally forever. Is this normal?
Should I have to wait until it assigns an IP address to use the correct nameserver?

I just moved my site from a shared host to a VPS with PhotonVPS.
I forwarded the name servers at my registrar, GoDaddy.
However, when I look at my INTODNS report, I am getting all sorts of nameserver errors:
[url]
Is this normal while the changes propogate? Or did I mess something up, because I also cannot access my VPS cpanel now.

Have you come across this problem where you change the NameServer IP in '/etc/nameserverips' but the change does not reflect , instead it reverts to the old IP?
Doing the following fixed the issue for me.
Disable whois lookups for the nameserver ip manager via in WHM>Tweak Settings

Say a person has a domain called mydomain.com
and this domain mydomain.com is hosted from a nameserver called ns1.mydomain.com and ns2.mydomain.com
will this mean that:
the person who own mydomain.com owned his/her own webhost server?
and is that what is being called dedicated server? where I already did some research that would mean the whole server is owned by the 1 person/domain only?
I have been asking question to myself quite sometime now.. and hoping that this forum could help me in understanding this matter.

I just took out a VPS hosting plan with Hostican, but I'm a bit confused about whether I followed their instructions properly... please be patient
Their instructions said this:
Quote:
Please note that on our network a VPS is like your own private space on the network to work from. This is why we provide your account with two dedicated IP addresses that you will need to use to register your name servers with. Please view the below name servers and IP addresses that you should use to register them.
ns1.mydomain.com <==> xx.xx.xx.xx
ns2.mydomain.com <==> xx.xx.xx.xx
Now all my domains are registered with 1&1, who don't provide an option for creating private nameservers in their control panel. So, I created two subdomains (ns1 and ns2.mydomain.com) and then created A records for ns1 and ns2, pointing to the IPs supplied by Hostican. Then I changed the nameserver for my domains to ns1 and ns2.mydomain.com
After a couple of days, this seems to have worked - domains point to new VPS webspace and emails working. I'm worried whether I did this properly though, or whether I'm going to get problems in future with reverse dns and stuff?

And this is when I added a new domain in Cpanel.
Using nameservers with the following IPs: 66.21.113.11,66.21.114.11 Bind reconfiguring on serverprovider using rndc
Created DNS entry for mydomain.com
Should it really be 2 different nameserver IPs?

I just got a VPS, (unmanaged...eh), and I seem to be having a problem with nameservers.
The current IP for the VPS is: [url]
Its set as the shared IP in WHM, so everything is pointing to that. I asked my host if the nameservers ns1.thehobbylounge.com and ns2.thehobbylounge.com should work (that is the domain for the account I am running under WHM/cPanel), and I was told that this was correct.
However my registrar gives me a validation error when I put in those nameservers for my domain.
I tried to follow these steps: [url]
But they seem to be already done...I think thats if your server isn't setup at all.

can't seem to figure out how the whole nameserver/DNS thing works.
My VPS is registered under a domain, say mydomain.com. So my nameservers on the VPS are registered under ns1.mydomain.com and ns2.mydomain.com, both assigned to the two IP addresses for my VPS.
The problem is, I'm trying to figure out how to get mydomain.com to actually point to my VPS from my registrar. If I type in ns1.mydomain.com and ns2.mydomain.com, it's just pointing to itself so it doesn't work.

I has a reseller plan and I was using one of my domains as nameserver. I mean ziafat.com was my nameserver and one of my sites.
Now I transfered to a VPS plan. I want to use my domain as nameserver and one of my sites. I changed domain manage page like this:
ns1.ziafat.com
ns2.ziafat.com
on the bottom of page I clicked this:
If you want to create or modify a nameserver which is based on ziafat.com click here.
and entered ns1.ziafat.com and ns2.ziafat.com and two IPs of my VPS plan.
Now all sites hosted on my new VPS opening currectly just ziafat.com (priemery and nameserver) domain opening as a blank site!
I saw server technical created a reseller account with ziafatco username and all of my accounts are under ownership of that.

I'm uploading my files to this new server and will switch over to it later.. I alredy know how to change the Nameserver at registrar...
My question is that how I should name the Nameserver on this new server?
Because my old server has the name of following Nameserver;
---------------------
NS1.MYSITE.COM
NS2.MYSITE.COM
---------------------
And my new server has exactly same name as this!!
I went throught WHM and I need to assign IP address to this Nameserver on the new server, and what will happen if I assign this IP address to the same Nameserver as in old server?
In this case,
1) Should I change the name of Nameserver to something else, such as following?
---------------------
NS3.MYSITE.COM
NS4.MYSITE.COM
---------------------
2) Or should I use IP address instead of using this English name?
3) Or should I wait until all the files are uploaded and assign this IP address to this Nameserver on the new box? I wonder what will happen if I do this, because there would be 2 different IP address to the same Nameserver in this earth!

I have just gotten a dedicated server this month.
CentOS with DirectAdmin (thanks to WHT for recommending this).
My problem is, I cant seem to "make" a nameserver and get it to work?
I have attached some .jpg. screenprints which I hope will help resolve my problem.
I hope you will look at the pictures and tell me what I am doing wrong.
I have followed the guide in DirectAdmin forum for creating a nameserver, but I still got problem. (I have not been able to post in there forum, cause I have not gotten a activate mail yet, so while I wait for that, I hope you will help me.)
I have waited a couple of days for the dns nameserver to update, but it is still not working.

I was with VPS Host A. When I wanted to have my domain name on the VPS from Host A, I simply entered the primary & secondary nameserver names at my registrars site and it was done.
Host A's service was poor, so I've started with VPS Host B. they created nameserver names for me at Host B's DNS for my VPS.
When I went to my Registrars site to entered these nameserver names, I was instructed to create an A record and a subdomain for each nameserver name.
I don't understand why it was simple with the first set of nameserver settings but not the 2nd ones.
The domain name for my first vps is different than my second vps.
The nameserver names from Host A didn't include the doamin name, for example Host A's were ns1.computer.com and ns2.computer.com and the nameserver names from Host B were ns1.mydomain.com and ns2.mydomain.com.
Could it be that it wasn't easy the second time because the nameserver names included my domain name?
