2. Use this information to work backwards to, for instance, put an IP address
on a spot that came in on a PC11 before any PC61 or PC62 A arrived. That
IP address may be on a PC61 for a different spot that had come previously.
+
+ An IP address that has not come in on that PC61, but is deduced from route
+ or user login information is mark in the debug with a '*'
3. Show which debugging category triggered any debug output. Debug output
that was not trigger, but just output (e.g. the startup stuff) has no
category.
+4. IP addresses are stored in hash tables in the user record permanently as an
+ IP address + time tuple. A pruning mechanism will appear when need arises.
