The OID (Object Identifier) field in a request is typically encoded using the ASN.1 (Abstract Syntax Notation One) format. This is a binary encoding format that consists of a tag, a length, and a value. The tag specifies the type of data being encoded, such as an OID or an integer. The length specifies the number of bytes in the value field, which contains the actual data being encoded.
For example, if the OID being requested is “1.3.6.1.2.1.1.1”, it would be encoded as follows:
06 08 2B 06 01 02 01 01 01
- 06 is the tag for an OID.
- 08 is the length of the OID value in bytes (8 bytes).
- 2B 06 01 02 01 01 01 is the actual OID value in binary, with each number encoded as a single byte.
