How about using scan?
If the variable string is set '9net.tcp://sub.domain.com:12345/abcdefg' or 'sometotherstuff9net.tcp://sub.domain.com:12345/abcdefg/lkjsdflkj/sdfl' etc then try using
scan $string {%*[^/]//%[^:]} fqdn
this results in a new variable $fqdn of 'sub.domain.com'
You can test it out by using the tclsh
% set string "lkasdflkjwe234239net.tcp://sub.domain.com:12345/abcdefg/sdlfkjasf" lkasdflkjwe234239net.tcp://sub.domain.com:12345/abcdefg/sdlfkjasf % puts $string lkasdflkjwe234239net.tcp://sub.domain.com:12345/abcdefg/sdlfkjasf % scan $string {%*[^/]//%[^:]} fqdn 1 % puts $fqdn sub.domain.com

FYI I'm just starting to play with scan so YMMV.
