rawdns a small DNS client library that performs A records queries against a given nameserver.
It relies only on net to perform the UDP queries, constructing and parsing all the messages in transit manually.
This is a project that is not intended to be used in production at all. It's not as efficient as it should and does not handle all the cases you'd expect from a production-ready library.
For real use, see miekg/dns.
CLI:
rawdns example.com
msg sent labels=[example com]
&{ID:0 QR:1 Opcode:0 AA:0 TC:0 RD:1 RA:1 Z:0 RCODE:0 QDCOUNT:1 ANCOUNT:1 NSCOUNT:0 ARCOUNT:0}
