Close.
It's actually 0:0:28:182:27:202, and is the Mac Address of the system
concerned. This OID translates to
BRIDGE-MIB::dot1dTpFdbAddress.0.0.28.182.27.202
and is the index of the Forwarding Database (dot1dTpFdbTable)
BRIDGE-MIB::dot1dTpFdbPort (mib-2.17.4.3.1.2) will report which port
traffic for that particular Mac Address will be sent to.
You'd need to use another lookup to perform the Mac<->IP mapping
(e.g. the ipNetToMediaTable of some well-connected system,
probably *not* the switch itself). Or use a local database.

That would be the DISMAN-NSLOOKUP-MIB.
It's not particularly widely implemented, AFAIK.
