NAME
       dns_name6 - look up host name

SYNTAX
       #include <dns.h>

       int dns_name6(stralloc* out,const char* ip[16]);

DESCRIPTION
       dns_name6 looks up the domain name for the 16-byte IPv6 address in ip. It puts the (first) domain name into out and returns 0. If the rele-
       vant ip6.arpa domain does not exist in DNS, or has no PTR records, out will be empty.

       If dns_name6 has trouble with the DNS lookup or runs out of memory, it returns -1, setting errno appropriately. It may or  may  not  change
       out.
