Hello Everybody,
Why enum module is not capable of parsing a response to a
naptr query if this response donīt have any Authority and Additional RRs?
When it receives some response like this one, it work well:
Domain Name System (response)
Transaction ID: 0xbe8b
Flags: 0x8580 (Standard
query response, No error)
1... .... .... .... =
Response: Message is a response
.000 0... .... .... =
Opcode: Standard query (0)
.... .1.. .... .... =
Authoritative: Server is an authority for domain
.... ..0. .... .... =
Truncated: Message is not truncated
.... ...1 .... .... =
Recursion desired: Do query recursively
.... .... 1... .... =
Recursion available: Server can do recursive queries
.... .... ..0. .... =
Answer authenticated: Answer/authority portion was not authenticated by the
server
.... .... .... 0000 =
Reply code: No error (0)
