[lug] Local DNS required?

[Anders Knudsen]

Background: my brother owns and manages a furniture store, and just got
broadband access to his showroom. With this came 5 static IP addresses.
He already has a domain name, and is using a webhost to serve up a
static intro page with a real website in the works.

Question: Now, with this domain name, what is the easiest way to get a
DNS entry to use his new IP address, thereby allowing him to run a web
server, and a mail server, running linux, locally (in the building?) I
guess my question is, are there DNS'es out there where you can just have
your domain name resolved to the IP address you choose? Or, would he
have to run a proper DNS in the building?

TIA,
