DNS subdomain

Hi All,

I have a server here on my office's net connection that I'm using for CVS repositories and vhosting of variuous checked out copies of websites. I would like to operate this on a public domain so that we can log in externally.

Currently the company domain is hosted by a third party hosting provider, on say

www.ourcompany.co.uk

I would like

local.ourcompany.co.uk

to be the machine in the office, but (here's the crucial bit), we then need to be able to create subdomains within this domain, eg

developername.projectname.local.ourcompany.co.uk

So in short I want the DNS server that is authoritative for ourcompany.co.uk to refer requests for *.local.ourcompany.co.uk to another DNS server that I will run locally which will be authoritative for local.ourcompany.co.uk.

The question is this: What changes do I need to request to our externally hosted DNS in order for this to happen?

Many thanks,

Andrew

Tell them you need to delegate local.ourcompany.co.uk to say, ns1.local.ourcompany.co.uk and ns2, respectively and provide the IP addresses of ns1 and ns2. The A record of local.ourcompany.co.uk will be handled by ourcompany.co.uk, remains unchanged.

Many thanks for that - it directed my googling nicely. As I understand it then, to delegate a subdomain, one needs to set an NS record in the higher-level DNS server, which then forwards requests for more specific addresses to the lower level DNS.

Now I just need to make all that work...

One way you and be certain that you can make such changes to the domain is to have your DNS with a service that provides you access to the zone file. Some Registrars offer the service, but third parties also do it. UltraDNS is one of them. It's rather inexpensive if you want to have that kind of control.
