Please excuse the wall of examples.

Currently all versions of AIX rely on netstat -i processing (Python2 and Python3) as the _uuid fix is only in Python3.7.
What is available on AIX 5.3?
As AIX 5.3 (and all earlier versions) lack uuid support, AIX depends on the output of netstat -i to get the mac address of the current system. Currently, the implementation is wrong because of the search for the colon (':') character. DETAILS/Examples FYI: arp -an can return the MAC address of a remote system, but not itself - and this does use the colon. Maybe this is the origin of the confusion. $ arp -an ... ?
