Can A Nameserver Be Specified In An A Record By Another Nameserver
Apr 4, 2008
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:
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.
I always thought that i can just go and point nsa.mydomain.com and nsb.mydomain.com A hosts to my personal dns server from my mydomain.com's dns service and use them anydomain.com's name servers.
But today i've been trying to setup another domain (mynewdomain.com) with a different registar and decided to use ns1.mydomain.com and ns2.mydomain.com as name servers and setup A host names. when i try to add name servers ns1.mydomain.com and ns2.mydomain.com to mynewdomain.com i get error saying name servers not registered. i could only do it by going mydomain.com's current registrar and add name sevrer records ns1.mydomain.com and ns2.mydomain.com.
now, i dont want to know why this is but my question is if i register ns1.mydomain.com and ns2.mydomain.com at my registrar , would they resolve like a current A host record? do i need to add a records at my dns service for those name servers too? if they do resolve without adding A records, instead of usiong dns service why i dont just add more nameserver records on my registar and use them like a records?
I have a dedicated server with Hostgator and I want to point img1.smackjeeves.com to img1.smackjeeves.com on my Dreamhost server. Dreamhost tells me what nameservers to use for smackjeeves.com, but my Hostgator server is already serving as a nameserver. Can I have my main DNS record point to Dreamhost's DNS only for img1? Or do I need to have my img1 mimic Dreamhost's DNS for img1?
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?
For some reason in WHM (root) (Fresh install) I'm trying to add a name server into ":2086/scripts2/listassignednsips" area and it just loads.... Never errors or anything just loads and loads for 30 minutes and never adds it. I have already add the IP's to the server. (6 IP's)
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
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.
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?
My dating site sends an email notification to the user when they receive a message on the site. Many of the notify emails arent going to their destination.
In exim, I keep seeing this message:
failed for 550-unrouteable
mail domain "ns1.mydomain.com" 550 Sender verify failed
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
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 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?
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!
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?
check that my nameserver settings are correct for the following (some registrars do not allow me to change the DNS on some domains as it reports an error):
My provider just gave 1 IP and to be use as shared IP for every accounts created in the server. I also assigned that IP for my nameserver ns1.domain.com at my registrar.
I was instructed also by my provider to use the next IP for the second nameserver which I also created at my registrar and created dns zone at the whm. All of the domains using that two IPs are working but I dont know why when I ping the second dns its not working. from Intodns.com its also showing nameserver 2 as an error..
My question is, do I need to add the second IP on the server/whm? you see when I go to WHM and click Show IP Address Usage I only see the first IP shared to all other domains. Somehow I'm expecting to see the second IP on the screen.
Anyone can enlighten me? the server I got should have been a full management but my provider is somehow responding so slow.
I have a dedicated server with WHM 11.23.2. I am in the process of "attempting" to change the hostname for a group of websites and also the nameservers.
Let's say for practical senses that these were the old details: Hostname: abc.example.com Nameservers: ns1.example.com and ns2.example.com
I changed in the following sections of WHM..
Server Configuration -> Basic cPanel/WHM Setup -> Hostname to 123.newsite.com
and then...
Networking Setup -> Hostname to 123.newsite.com
and then...
Server Configuration -> Basic cPanel/WHM Setup -> Primary Nameserver to ns1.newsite.com and then...
Server Configuration -> Basic cPanel/WHM Setup -> Secondary Nameserver to ns2.newsite.com.
Then...
Networking Setup -> Nameserver IPs. I deleted the old ones and created the two new ones: ns1.newsite.com and ns2.newsite.com.
I have double checked that this information is still there. Obviously newsite.com is listed as a domain/account. However, example.com was naturally the first one associated with this server.
I performed a server reboot, apache reset etc.
This was three days ago. I assumed it had all changed over. Until I (stupidly) remembered that I hadn't changed the goDaddy information to point to these new nameservers. I panicked thinking all the sites (six of them) would be down. However, they weren't. When I tried to change the nameserver information for a domain in goDaddy it came back with errors... it would only accept ns1.example.com and ns2.example.com.
So, I did a tracert to the IP address of the server and indeed it comes back as abc.example.com. Every domain is associated with that static IP.
I can't even find anywhere where abc.example.com is listed within the WHM. All the new values are listed... so, where is it pulling this from? I thought the reset of the server (as a graceful reboot) would resolve this issue.. it hasn't. I've rebooted twice and awaited the thirty minutes for everything to get back online. No success.
The zone for the root domain splinteredmedia.net is missing, or could not be read. The ip address will be read from the webserver configuration and a new zone will be created for this subdomain. Bind reconfiguring on smpl using rndc Error reconfiguring bind on smpl: rndc: connect failed: 127.0.0.1#953: connection refused Created DNS entry for ns1.splinteredmedia.net
Is the error i get when i try to add a entry for one of my nameservers.
I have cPanel on a CentOS 5.1 VPS
I am still pretty new to CentOS
how would i go about adding a zone and if somebody cpuld point me to a place where i can read exactly what it is and how to set it up i would be very grateful
I have just purchased a .info domain just to use for playing about on.. I purchased it from 123-reg.co.uk. I have 3 other domains with them but these are .com, .co.uk and .org.uk domains. All pointing to my VPS nameeservers..
For some reason when i goto add my nameservers to the .info domain it says Error text: Nameserver ns1.playcontrol.co.uk doesn't exists in the registry Error text: Nameserver ns2.playcontrol.co.uk doesn't exists in the registry Ive not encounted this before. My friend purchased a .co.uk domain last night and when i added the nameservers to his it worked fine.
