I am not sure where either. But DJB noted to bugtraq
<20020704164247.30990.qmail at cr.yp.to> a while back that:

  The .[ch] files (dns.h, dns_dfd.c, dns_domain.c, dns_dtda.c, dns_ip.c,
  dns_ipq.c, dns_mx.c, dns_name.c, dns_nd.c, dns_packet.c, dns_random.c,
  dns_rcip.c, dns_rcrw.c, dns_resolve.c, dns_sortip.c, dns_transmit.c,
  dns_txt.c) and all necessary lower-level .[ch] files are now in the
  public domain.

This is also mentioned at http://cr.yp.to/djbdns/res-disaster.html

Looking at this source (djbdns-1.05), I don't see any copyrights or
licenses in any of these individual files.

I have no answer; I do not (knowlingly) use SRV records.

I haven't looked at it closely. I just read that it is "designed to
replace the old BIND res_*/dn_* library" at
http://cr.yp.to/djbdns/blurb/library.html.

I don't know how easy it would be (or if it would be worth it) to create
wrappers.

Anyways, I am curious if anyone uses it (or has tried it) as an
alternative.
