Erik Ekman cde0b7632d Set additional record count properly in NS reply

 2020-07-23 22:12:07 +02:00
Erik Ekman ec6a1ac308 Fix IPv4 address in replies to A or NS queries (github issue #38) 
The destination field in struct query was changed from in_addr_t to
struct sockaddr_storage, wihtout updating the functions sending it
in src/dns.c.

Only add extra A answer for NS queries if destination refers to an
IPv4 address, and fail if trying to encode a reply to an A query
if destination is not IPv4.

This means NS requests received over IPv6 will not contain an address
and A requests will be ignored, unless the -n option is used, or the
www subdomain is requested which sets a fixed address (127.0.0.1).
