I currently have a server with 2003 sbs exchange server and everyone's email address is xxxxxx@dddd.net.  I now have a another domain name that I want all the email addresses to also receive from.

For example:

My email address is jondoe@abc.com

I just bought the domain name def.com

I want it so if anyone emails jondoe@abc.com or jondoe@def.com that it comes to the same exchange mailbox.

What exactly do I need to do?

Make sure your domain's MX record points to your Exchange server (or SMTP gateway).
Then you add the new domain to your recipient policy. This step is required for Exchange to except e-mails for the new domain.
Everyone can get several SMTP addresses. Only one is their primary. This is indicated by capitals (SMTP instead of smtp).
Hope this answers your question.

You need to add the %user%@def.com address as a secondary email address for every user.

You can do this 2 ways. Use the command LDIFDE to add the 2nd email address to each user on your domain.

Create a Recipient policy on your Exchange Store that automatically configures your user's email addresses

Recipient policy configuration

LDIFDE usage
(The actual attribute to edit is proxyAddresses:)

Let me know if you want a script built to import addresses for you. (But I would go with the Recipient policy option)

(Also, I am assuming you have configured your mail eXchanger records so that email can actually be routed to your gateway)

Creating (or modifying) the recipient policy is not optional, but mandatory. If you don't have the new domain in one of your recipient policies, Exchange won't except e-mail for this domain

When they say I need to give the ip address of my exchange server, is that simply the ip address of the network.  The same ip address I would  get if I was on their network and typed in www.whatismyip.com?

The IP address of your external gateway. so whatismyip will be an option
