Are * wild card SSL certificates expected to or required to only be used by 1 IP?

Such that is on ServerX

and is on ServerY

where both servers have unique ip addresses. Is this valid to share the * certificate across these servers?

You can use a wildcard certificate with multiple subdomains across multiple IP addresses. While there is no technical limitation, often Certificate Authorities have licensing restrictions on thier usage.

I did not realize the single ip facet was a licensing issue, with this information I was able to determine that RapidSSL certificates do not come with this restriction. – Chris Marisic Oct 21 '10 at 17:52
