netstat output truncates octets?

    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            TIME_WAIT
    tcp        0      0       yyy.yyy.yyy.yyy:1914      ESTABLISHED
    tcp        0      0        yyy.yyy.yyy.:1912        TIME_WAIT
    tcp        0      0        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?
