como está escrito lá. Por exemplo:
user@host:~$ ifconfig eth0 Link encap:Ethernet HWaddr 04:00:32:00:00:01 inet addr:170.0.0.0 Bcast:170.0.255.255 Mask:255.255.192.0 inet6 addr: fe80::999:zaga:fe78:7901/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:11857875616 errors:0 dropped:0 overruns:0 frame:0 TX packets:8490937839 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4817771645749 (4.8 TB) TX bytes:2541531991948 (2.5 TB)
