Project Honeypot

Project Honeypot is a nice resource to look for historic behavior of suspect IP addresses.

MVRP

I was in the process of researching a VLAN propagation protocol when I found out it was superseded by a newer standard - MVRP. This is an IEEE competitor to VTP (which is Cisco proprietary, if you didn't know). The IEEE document is here. To be honest, I was hoping for an MST and VTPv3 migration.

More traceroute fun

Darren at Darren's CCIE mission has another interesting item on traceroute with more information on the OS overhead (read: Windows overhead) in performing traceroutes. I have to assume this might be inherent to Active Directory (especially the DNS PTR record lookup) since it is so DNS dependent.
