Domain question?

Hi all,

I have the following question.

First: domainname->Ip-address.

We have a dominoserver that contains our whole website (html and .nsf). Address f.i. www.ourdomain.com → Ip-address 1

We want to host our website (html only) externally. So www.ourdomain.com is taken over by this machine. → Ip-address 2

But we do want to access the .nsf files on our dominoserver (Ip-address 1). Is it possible to create a subdomain old.ourdomain.com that routes to Ip-address 1) so it will be possible to access the Notes databases.

Thanks, in advance

Hasan
