dns namespace

[kanoz]

I am planning on setting up network and am unsure of the best DNS design.

The network consists of the following:

1 x Win2k Advanced Server
- IIS5 hosting corporate website
- Exchange Server
- AD integrated DNS
- Internal DNS Server that forwards external DNS requests

1 x DSL Hardware Firewall/Router
4 x Win2k Professional Workstation

I have registered a domain with INWW. What is the best option for me to use as an internal namespace? Should i have the same as the external namespace (eg: company.com), a subdomain of the external domain (eg: internal.company.com), or another name altogether (eg: soho.local)?

Got to this forum http://x220.minasi.com/forum/default.asp and do a search for "split brain dns" without the quotes. You can use the same name internal and external if you set it up properly. Its called split brain dns.

I'm not sure of the bets, but I use the same internal and external but actually keep the DNS records on different machines (as to not help reduce security risks to the LAN)
