Domain DNS

I have a registered domain at a web hosting company that has a static IP address. I am going to implement an office network (windows server 2003) with DSL (also with static IP)and want to utilize VPN connections and Exchange server 2003. I will be creating a domain for the office network and deploying active directory. I am confused about how to maintain one primary namespace with DNS with 2 static IP numbers. Would I use my static web hosting IP address with my network domain but change the subnet mask 255.255.255.001 in order to maintain the same domain name? Or would I use the static IP of the DSL connection when setting up my network domain? If so, how can I keep the same domain name that points to the web hosting IP? My goal is to have one DNS namespace. I am confused about how to to merge the two and still keep the primary domain name.

You can set up your AD domain name however you wish - office.yourdomain.com
if you don't want to share the namespace. Or you can use the same domain
name - yourdomain.com - and add a host record in your DNS like www that
points to the public IP of your public web site....

Your own network's IP addresses really have nothing to do with this - but
get a good firewall/router that can do NAT to protect your network and allow
you to use private IPs internally. Your DSL router can do NAT but won't
provide much protection from the Internet.

Thanks Lanwench. I appreciate the info. I am assuming now that whether I share (www.yourdomain.com) or not share (office.yourdomain.com) my namespace that it will not make any difference with configuring Exchange Server to work with addresses of (E-Mail Removed)?

Nope - all Exchange cares about is its recipient policy/policies.
