cnames?

[TrXtR]

Just a question.
If I'm not wrong about dns, it only works on the actual domain name, and not the cnames. If a isp 'isp.co.za' gives his user a static like cname, like 'trxtr.isp.co.za' it would be really nice (is that possible?).

But I'm wondering if it's possible to register a domain to point to the cname, or is that only possible with ip addresses?

But yeah, if the cname thing could be done, I'd be very happy.

I dont understand what you are asking exactly. A cname is a common name for a different domain name "trxtr.isp.co.za in CNAME isp.co.za" for example.

You can register a domain on a cname that points to a name server. Most of MWebs dns servers are cnamed.

Do you mean a reverse dns maybe?

Since 20 November 2002 UniForum does NOT allow you to use CNAME entries to register domains with.

Hi

Cnames has been discontinued for many reasons but not becouse of static
IP adresses.

There are no way of registering a domain name with it on atleast 2 dns
nameservers.

Static IP addresses? No man, that's what I think is sentech's problem, not yours. And well I just dont get that last piece.

But yeah, they just dont want to. So that sucks, that's somthing in my opinion that actually could save static ip's. So why not do it?
But I dont run uni-form, so I wouldnt know.

But worth a try, it would be really nice.

flashvc : Thanx for the article, makes my eyes open wide.

Karnaugh: Basicly, sentech, rather than giving me a a static ip-address, they just make sure I always get the cname me.sentech.co.za. And then I register me.co.za and point it to me.sentech.co.za and walla, I have my own domain.

Bummer though

Dude you are way confusing CNAME and A records.

The refference of UniForum to CNAMEing is by registering a domain where uniforum create the domain as a CNAME to another host insted of an SLD for which some nameservers are authoritive. The reason they dont offer this is because people can simply register 12304809128340912 domains without having the propper servers etc and then they try to sell them off to people, this wastes domains which could otherwise be used for a usefull purpose.

There is no way sentech could ensure you have a fixed domain pointing to your address unless you were assigned a static IP and they added an A record (and possibly PTR's in the reverse situation) to reflect that IP.

You can get a dynamic DNS service like 'asmith' just mentioned for which you run a client that constantly updates a remote A record to reflect your current IP address. That is probably what you want - You can also register a domain on that IP address and run your own domain name servers, you may have problems so if you do that you must run a low TTL on your nameservers (3600s works for me).

DNS is named the "Black Art" of the internet []
