octets. If multiple methods are defined, then it is recommended
that the first octet indicate the method being used and the
remaining octets be a function of the method.
3. 3) The length of the octet strings varies. The first four octets are
set to the binary equivalent of the agent's SNMP management
private enterprise number as assigned by the Internet Assigned
Numbers Authority (IANA).
For example, if Acme Networks has been assigned { enterprises
696 }, the first four octets would be assigned '000002b8'H. The
very first bit is set to 1. For example, the above value for Acme
Networks now changes to be '800002b8'H. The fifth octet
indicates how the rest (6th and following octets) are formatted.
The values for the fifth octet are:
