Difference Between A Cname Record And A Domain Pointer
Dec 17, 2006
I am seriously confused mainly because of the way it was explained in my training at work. Can someone please give me an explantion of the difference between creating a cname record and using a domain pointer? My understanding is that they both effectively do the same thing which is allow one ip address to be used for different domains.
Extra marks given for an easy to understand analogy as i'm definately a visual learner.
I have a domain hosted in a external pool of servers.I must set a dns record for www.domain.tld and domain.tld (without www). It must be done using cname.The www.domain.tld , works fine.
Ex:www.domain.tld IN CNAME xyz.otherdomain.tld.
But I am not able to set a DNS record for a root of domain.
Ex: domain.tld IN CNAME xyz.otherdomain.tld. neither domain.tld IN CNAME www.domain.tld.
The PPA didn't allow me.It say that the host field is mandatory.
I've been trying to get some domains parked using DirectAdmin's domain pointers. I've searched for threads about this on Google, and followed the instructions. I go to Domain Pointers -> Add New Domain Pointer. I put the domain into the form field (leaving 'Create as Alias' checked) and click Add. I've waited for a few days to make sure there were no caching problems, and the domains still didn't resolve. The nameservers on my domain registrar are set correctly. I've parked domains before on CPanel and it worked just fine.
When I create a CNAME record for domain, and then trying to load it, it goes to default website. It was working fine before, all old CNAME records are working fine.
Tried reconfigure-all but it doesn't fix the problem. I'm using 11.5.30 Update #44
OK, I am confused. I have one domain that is parked on top of another domain. I would like Mail that comes to the parked domain to be automatically forwarded to the same user name at the primary domain.
Can I change a DNS or MX record to facilitate this?
Differences between Websites & Domains and Webspaces
I'm a beginner in Plesk Panel and I've a "concept" question. So, which are the differences between Websites & Domains and Webspaces? There's some documentation about the definition of this three objects?
I have a site mydomain-name.com that is running and the mail server for it was mail.mydomain-name.org
However the mydomain-name.org has expired and I don't want to renew it. I just want to use the .com domain and have the mail use mail.mydomain-name.com
So i created the MX records for the .com domain .. Now my question is do i have to also contact my registar for the domain and ask them to update their records so that now it points to the new MX?
I am really new at this stuff so please bare with me.. when i do an nslookup in DOS it still shows the .org as my mail server.
mydomain-name.com MX preference = 10, mail exchanger = mail.mydomain-name.org
Is this something that needs to be changed at the registrar level?
I added a domain name through Plesk. after that I deleted it because I wasn't happy with the configuration and thought I'd just start from scratch.
now, I'm unable to add it. the domain is not listed with the other domains on the server, however when I try to add it I get "Such DNS record already exists".
Impossible to delete my PTR record (DNS) on a domain name. Message error: Impossible de restaurer la zone DNS : une erreur s'est produite en ajoutant l'enregistrement (IPv6 du serveur) IN none mondomaine.fr. : Des valeurs incorrectes ont été indiquées pour l'enregistrement DNS.
My server has been kernel panicking on and off irreguarly every 2 days or so since I upgraded to cPanel 11, I'm not entirely sure whether this was the cause however I've isolated the fact it is a kernel issue. I am running CentOS 4.5 and was running Kernel "2.6.9-42.0.8.ELsmp" however switched to the kernel I was running before (2.6.9-42.0.3.ELsmp) and the same issue is still cropping up.
I thought that it may be a memory addressing issue or the like, however from looking up the issue, several C programming forums seem to suggest dodgy applications, the memory usage on the server does always seem fairly low and loads are generally healthy so this would seem to be supported.
The logs before the server kernel panics are as so:

I am simply wanting to map on mydomain.com to anotherdomain.com. So i setup a CNAME on mydomain.com. Once propagated mydomain is not being picked up and is defaulting to the cpanel successfully installed screen.
I have tried this on another of our servers and this does work.
So my question is: can you use a CNAME to map mydomain.com to anotherdomain.com without having to add the mydomain.com to the apache VirtualHost ServerAlias?
It does seem like you can as i have this working on one server - is there an apache setting somewhere to block this?
I'd like to know how I can use DNS to do something like make a CNAME record that points the same address to different addresses based on the port used.
mail.example.org on port 80 points to ghs.google.com mail.example.org on port 995 points to pop.gmail.com mail.example.org on port 587 poitns to smtp.gmail.com
We have Livezilla tracking on our site, and saw some suspicious activity this afternoon from the Netherlands, about 5 connections from the same IP address, they now appear to have put in a cname record/copied our site for http://wiiee.nl/design.html to our site. Does anyone know what they're doing/trying to do?
The Non-Profit I work for uses IXWebhosting for our webhost and to manage email accounts. For the past 2 months whenever we send emails to anyone @baaqmd.gov, we receive CNAME bounceback errors. I have contacted IXWebhosting and they say that their DNS server's aren't registering baaqmd.gov and that I need to contact baaqmd.gov. Well I've been in constant contact with baaqmd.gov's IT guy and they are receiving emails just fine from outside agencies. In fact, when I send a test email using GMAIL to baaqmd.gov, they receive it just fine.
To further confuse me, we receive emails fine from BAAQMD.gov.
I am trying to change the cname through a batch.. It is successfully done for English language but I want to use Arabic language. When I am using Arabic it appear like this "????".
