I can reproduce this in Emacs 28...  but only intermittently.  Sometimes
it will hang completely, and sometimes I get the timeout.

This is the backtrace (with debug-on-quit) when it just hangs:

Debugger entered--Lisp error: (quit)
  make-network-process(:name "Whois" :buffer #<buffer *Whois*> :host 
"rs.internic.net" :service 43 :nowait nil :tls-parameters nil :coding nil)
  open-network-stream("Whois" #<buffer *Whois*> "rs.internic.net" 43)
  run-network-program("Whois" "rs.internic.net" 43 "facebook.com")
  whois(nil "facebook.com")
