all logfile I see IP server ip but there is no user

[f1h0]

I can not understand all logfile see only 1 server ip even when you connect the same server via ssh why? Where the ip address of the user?

scored a team w and I see though the server ip to be my ip user

root@stdvp:~# w
 13:17:18 up  1:38,  2 users,  load average: 0.00, 0.00, 0.00
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     tty1                      12:27   49:18   0.14s  0.08s -bash
root     pts/0    64.*.*.*   13:11    3.00s  0.06s  0.00s w

why is that?
