ircu/TRACE
Shows the route over the network from you to the given nick or server.
/TRACE [<nick>|<server> [<to server>]]
Parameter <to server> can be used to trace to the given server. Only opers can use wildcards to list users, but anyone can see all the opers, and only opers can get a remote listing of users and opers.
Trace reply for a user or oper shows their connection class, nick and user@IP, and seconds since something was last received from their connection (this is not the same as their idle time).
The reply for server shows its connection class, the number of servers reached via this link, number of client reached via this link, name of the server linked, who or what established this link, seconds since something was last received from this link, and the age of the link in seconds.
