Net.DNSBase.EDNS.OptNum

Description

The 16-bit OPTION-CODE field used by EDNS(0) options inside the OPT pseudo-RR (RFC 6891 section 6.1.2). Pattern synonyms cover the standardised options (NSID, ECS, EDE, ...); unknown codes round-trip as OpaqueOption values. See the IANA DNS EDNS0 Option Codes registry for the full list.
