I'm working on creating a self-signed SSL certificate and wondering if it is possible to create the CSR using an IP Address as the Common Name instead of a domain name. Is this possible?

I suppose you could, but that means anyone not browsing to your IP would receive a warning about a certificate mismatch.  That might not be a problem for you, since they'll already be receiving a warning about a self-signed certificate.

If you want a single certificate to answer to multiple domains, you need a wildcard certificate.  Those are useful in cases where you have a.mydomain.com and b.mydomain.com, and don't want to pay for two certificates.

Yes, you can.  As noted above, browsing to anything but the IP would give the error, but I'm guessing you know that.  

To correct above note, wildcards are for multiple sites inthe same domain, e.g. *.domain.com, not multiple domains.  If you want multiple things, e.g. IP address, hostname, and FQDN, you could look for a multi-domain cert, a.k.a. UCC cert from a commercial vendor.  If using your own CA, use the SAN: attribute to specify additional names in the Attributes field when submitting via certsrv page, or can use SAN when submitting via certreq.  Most apps only allow for one name when creating the CSR, although there are a few out there (sorry don't remember which offhand, but to my knowledge IIS is not one of them) that do allow for creating the SAN in the CSR also.

That's actually what I meant.  Thanks for the clarification.  :)
