Zone files always seem a bit of a black art to me so before I screw things up I thought I'd ask here.
My domain isbd.net is hosted at gradwell.net and I can customise the zone file.
The only change I have made is that I have added a CNAME entry for 'home' with a data value of 84-45-228-40.no-dns-yet.enta.net (note that this is a web form with columns for these values, it's not the actual raw zone file). This has been working fine for the past couple of years so I can access my home machine as home.isbd.net. The 84-45-228-40.no-dns-yet.enta.net is my EntaNet (via ukfsn) domain with a static IP.
However 84-45-228-40.no-dns-yet.enta.net seems to have gone AWOL, the DNS name that is, not the actual connectivity to 84.45.228.40. I've contacted them and they don't really know why but the names are about to be changed so maybe something has happened ahead of time.
Anyway I'd like to change things so that I can give the raw IP address for home.isbd.net rather than relying on Entanet's name for it, so my question is how do I do this? Do I need to add an A record instead of a CNAME, or do I need both, or what?
I suspect that all I need to do is to delete the CNAME I have added and then add an A record for 'home' with data 84.45.228.40, is that right?

Sound about right. As you say A records are for IP addresses CNAMEs for other domain names.

It seems to have worked OK, I just need to wait for it to propagate now as it hasn't reached everywhere yet.

Seems to work from here:
david@sid:~$ host home.isbd.net home.isbd.net has address 84.45.228.40

Ah, good. It seems to be working most places I can try actually except my system here at work:-
chrisg$ host home.isbd.net home.isbd.net is an alias for 84-45-228-40.no-dns-yet.enta.net. Host 84-45-228-40.no-dns-yet.enta.net not found: 3(NXDOMAIN) Host 84-45-228-40.no-dns-yet.enta.net not found: 3(NXDOMAIN)
We obviously have a long timeout on the DNS here! :-)
