missing zero's in MAC through snmpwalk

gday, running router OS 6.49.7 on RB750Gr3

snmpwalk results gives missing (starting) zero’s in MAC addresses

for example :
IP-MIB::ipNetToMediaPhysAddress.6.192.168.1.5 = STRING: 0:6:78:35:12:5b

The full MAC is (through /ip arp command)
9 DC 192.168.1.5 00:06:78:35:12:5B bridge

Is this a caveat or bug ?

Appreciate any response !

the mac is the same,this is not the Full MAC, just one different representation,

like
0x00FF00 = 0xff00
or
0000132548,50000 = 132548.5

This is quite normal in SNMP. It may be that the standard requires it, I don’t know. But I have had to re-format MAC addresses received via SNMP from other manufacturer’s devices as well.
