Parameters | id | A 16 bit identifier assigned by the program that generates any kind of
query. This identifier is copied to the corresponding reply and can be

response. If RD is set, it directs the name server to pursue the query
recursively. Recursive query support is optional. (type: int ) | |
recAv | Recursion Available - this bit is set or cleared in a response and denotes
whether recursive query support is available in the name server. (type: int ) | |
