I'd prefer to use string, which can be managed freely by the user, and be 
human-readable.  Unlike IP layer networking, we're not constrained by e.g. 
having to fit in the IP options, and can simply convey the DOI as-is.

This will also not prevent users from utilizing integers as the DOI if 
desired.

In the common non-DoD case, people should be able to configure the DOI as 
simply as editing a configuration file to set the DOI to a domain name or 
arbitrary realm name.
