Alan, thanks! So in short, looks like sometimes the returned values are actually formatted based on MIB files. However, while I modified the "InetAddressIPv4" or "InetAddressIPv6" terms in INET-ADDRESS-MIB.txt MIB file or "PhysAddress" and "MacAddress" terms in SNMPv2-TC.txt file, it had no affect to returned values. For example if I changed the DISPLAY-HINT for "InetAddressIPv4" from "1d.1d.1d.1d" to "1d:1d:1d:1d", then all the requests made for IPv4 addresses were still formatted in "1d.1d.1d.1d" notation. On the other hand, the DESCRIPTION for "InetAddressIPv4" term says that "This textual convention SHOULD NOT be used directly in object definitions". So correct me if I'm wrong, but while it is possible to define the format of SNMP GetResponse values in MIB files, such conversions are in practice usually not done in MIB files?
