No
Two different hosts

Host one I create a subdomain of the domain that lives there

Host two i creat an account for the subdomain and get the IP

Host one I create the A NAME as the subdomain. and host twos IP

Should the subdomain then point to host two?
 
exactly the above.. create a subdomain and have it point to a diferent host

only needing http

dns records can take up to 48 hours to fully propogate to all ISP/DNS servers

News ones should be instant, or at least as soon as the authoritiative nameserver reloads its zone files. If it didn't previously exist it can't have been cached, so will trigger a lookup to the authoritative server immediately.

Changes will take up to seven days to propogate, as some cacheing nameservers ignore the TTL set by the authoritative nameservers and impose their own (often 168 hours). This is REALLY ANNOYING if you do everything properly when moving a server to a different IP address (reduce the TTL to 10 minutes several days before, etc) and still the change takes up to a week to propogate.

yup should do, wouldnt be uncommon for new ones not to work for up to 48 hours :) never really had any that didnt work after that.
 
Thanks guys I know DNS can take time to propogate.. although 48 hrs has been the figure far many yrs and it rarely takes anywhere near.

The reason I asked was.. I had never done this with a subdomain .. so rather than wait hours I wanted confirmation I was on the right track.. But before anyone coul.d. it propogated to my isp in 20 minutes :)
 
sub domains don't really need propogation as requests will hit your domains DNS server that knows of your new sub domain. Your ISP only has to know the DNS server for your domain which will tell it there is a new subdomain. It is as you figured out not far off immediate

New domains are a problem as they don't know the domain or the DNS server associated with it, this take a while to propogate through all the servers.

As you can see though..the new dns was to a completely different host for the subdomain .. surely that has to propogate.. all isp still have to update
 
nope

your request for www.talkphotography.co.uk is often cached by ISPs etc., but every so often a request still goes through to the talkphotography.co.uk DNS server, to check its not moved.

If you request kipax.talkphotography.co.uk, your machine, router and ISP don't know directly where it is, so it hits the authortive talkphotography.co.uk DNS server to find out where kipax..... is. It doesn't matter where it is hosted, your authortive DNS server knows where it is.

Once the request goes through, your PC, router and ISP may start caching it for you.
 
Cheers Dale.. I just thought I had a really quick ISP :)
