ipv4 only? probably it's better to use ip2tuple_v4 #Resolved

Probably it's better to compile this regexp in init?
Also is it possible to extract this value from string using something like
if_name.replace('Ethernet', '') ? #Resolved

Let's keep it for readability and optimize if we find it on critical path. re library has the opportunity to hide the optimization without users changing code.

machex = ''.join(chr(b) for b in mactuple) should work for you #Resolved

Should we remove this line? What to do if the mac is 0? #Resolved

The correct behavior of incomplete ARP entry (an IP without MAC) is not clear in the protocol. ref: http://cric.grenoble.cnrs.fr/Administrateurs/Outils/MIBS/?oid=1.3.6.1.2.1.4.22.1.2
Just keep the code here for further refinement, if needed.
