netstat output truncates octets?

[elkram]

Here's something I just noticed. It is reproducible.

When I run netstat -nt in a command shell, the final octet of the remote address often is missing. Sample output:

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 127.0.0.1:35753         127.0.0.1:80            TIME_WAIT
tcp        0      0 xxx.xxx.xxx.xxx:80       yyy.yyy.yyy.yyy:1914      ESTABLISHED
tcp        0      0 xxx.xxx.xxx.xxx:110        yyy.yyy.yyy.:1912        TIME_WAIT
tcp        0      0 xxx.xxx.xxx.xxx:110        yyy.yyy.yyy.:1913        TIME_WAIT

Note that the foreign address in the botton 2 rows is yyy.yyy.yyy. instead of yyy.yyy.yyy.yyy . I think it happens only for incoming pop connections on port 110. Other ports display all four octets. From the same IP address, the longer 4 digit WHM port of 2087 does not drop the final octet, nor does the shorter 2 digit HTTP 80.

Has anyone else seen this? Any ideas as to possible causes?

Thanks.
