Description rlucia 2000-10-11 17:10:01 UTC 
After changing IP address and netmask on an ethernet interface, outgoing connections or icmp packets echo request still maintain the previous address. The routing table changes accordingly. I'm using an xl interface.

How-To-Repeat: change the ip address:
  ifconfig xl0 inet newaddress netmask netnetmask
then monitor things simply with:
  ping anotheripaddress
  tcpdump -n icmp
