Earlier today I glanced through the dnsdist docs and saw some rules for balancing based on IP addresses. It wasn't immediately clear how I might determine backend IP (and port?) based on query name, but someone else suggested off-list that it was possible. I suppose I might need to spend some time looking through the docs and finding some solid examples.</div><div class=""><br class=""></div><div class="">I also looked have looked at PowerDNS for specifying a DNS server backend, but again it wasn't clear to me from reading through the docs if that was possible. The BIND backend, for example, seems to use a BIND configuration file, but doesn't actually query a BIND (or other server) backend.</div><div class=""><br class=""></div><div class="">I also looked at using LUA records, but I'm generating TXT records based on the query name, and I also wasn't sure if that was possible with the PowerDNS/LUA, at least it wasn't clear from the examples.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Casey</div></body></html>
