Yes, but they are usually called UUIDs (Universal Unique IDentifier).
As Alex pointed out, it's likely that Gnutella assigns a UUID for your
account or session or something like that. These values are random,
and designed to guarantee uniqueness. See RFC 4122 for details on how
they are supposed to be generated[1].

Your system should already have libuuid installed. There is also a
command line tool you can use to generate UUIDs in shell scripts (sudo
apt-get install uuid), as well as libraries for Perl and Python.
