network problems

I have installed freebsd 8 beta 2 about six days ago, and yestarday began problems with network.

In /etc/rc.conf i disabled all services such as nfs, apache, dbus, samba and so on (may be this problems due to it).
When i try ping 10.55.102.1 it says
sendto: Invalid argument

And in dmesg output very much this lines:
ipv4 address: "10.55.102.1" is not on the network
ipv4 address: "10.55.102.1" is not on the network
arpresolve: can't allocate llinfo for 10.55.102.1
