it's really weird my netstat show an host in the routing table that is
not in rc scripts... is possible that this host is trying to do something
strange like... getting my IP address or something ??
someone can have an idea on why my routing table is like that ??
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif
Expire
default 137.204.49.254 UGSc 55 265 ep0
127.0.0.1 127.0.0.1 UH 2 6457 lo0
137.204.49/24 link#2 UC 0 0 ep0
137.204.49.17 0:20:af:b7:21:d9 UHLW 3 140397 lo0
137.204.49.30 0:60:8c:92:ae:a2 UHLW 0 10 ep0
1082
137.204.49.254 aa:0:4:0:1a:95 UHLW 56 0 ep0
428
my host is 137.204.49.17
the other 137.204.49.30 is a PC on the same lan and I do not know why it
is in the routing table noone added it and it is not in rc scripts as
a default route or alternative route path, so I do not understand
can someone help me ?

it is really weird
here is ifconfig -a

ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 137.204.49.17 netmask 0xffffff00 broadcast 137.204.49.255
ether 00:20:af:b7:21:d9
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
here is netstat -nr here is the weirdness
