actually...i'd suggest doing it with the pcb address.  it gives less
false positives (as, for example, 993 may be part of a pcb address).

    % netstat -Aan
    ...
    f0a1ff00 udp        0      0  *.4785             *.*
    ...
    % fstat | grep f0a1ff00
    root     named      10287    8* internet dgram udp f0a1ff00

or lsof, since that allows you to find out in a more direct manner.

    % netstat -an
    ...
    udp        0      0  *.4785                 *.*
    ...
    % lsof -iUDP:4785
    COMMAND   PID USER   FD   TYPE     DEVICE SIZE/OFF NODE NAME
    named   10287 root    8u  inet 0xf0a1ff00      0t0  UDP *:4785
