Mac Server bizzare routing table

view story

http://serverfault.com – My mac routing table usually is very simple. I know it's based on bsd , but what's it doing or trying to do. My routing table is usually very simple however, the second one, default was point to link5 ? Is this normal, or is this IPV6 craziness at work? Can somehelp me understand what OSX/BSD is doing? nternet: Destination Gateway Flags Refs Use Netif Expire default UGSc 22 0 en1 127 UCS 0 0 lo0 UH (HowTos)
