Greetings. Has anyone else tried to communicate with TSIG using HMAC-SHA224 between BIND and other DNS implementations? I'm using Perl's Net::DNS and BIND 9.6.1p2 and I'm able to sign messages with TSIG using HMAC-MD5, HMAC-SHA1, HMAC-SHA256, HMAC-SHA384, and HMAC-SHA512 successfully. But HM

Ok I think I've figured this out as I did a little test to change the IP within the remote authoritative DNS server to 172.16.1.100. of course there is no machine at that IP address within my networks but there was some address confusion as the DNS server had the same IP address as the rad
