WCF is using the computer name instead of the IP address and cannot be resolved

This is what worked for me. In config file

< serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
< / system.serviceModel >

If it is set to false, I was getting that crazy computername substitution.

multipleSiteBindingsEnabled="true" seems to be all that I have to do for this to work as it should.
