@jpmens
@jpmens: consultant, author, architect, part-time admin, small-scale fiddler, loves DNS,
MQTT, plain text, and things that work. Thought up OwnTracks, and made jo.
a selection of open source DNS servers authoritative or recursive
(or both)
None
dnsmasq recursive, authoritative for /etc/hosts, DHCP (v4, v6), DNSSEC
validation
Unbound local-data, DNSSEC, dnssec-trigger, +win32, embeddable, fast, rate-limiting, extensible with
Python, qname minimization
NSD 4 very fast, TSIG + DNSSEC, zone compiler, root,
addzone/delzone, and RRL
BIND full reference implementation, TSIG, DNSSEC, +win32, SDB, DLZ,
RFC 2136, ram-hungry, RPZ, views, RRL
BIND 10 completely different. Python, C++, REST, DHCP
PowerDNS authoritative lots of back-ends (SQL, LDAP, pipe), DNSSEC,
master/slave/ native, supermaster, pdnsutil
PowerDNS Recursor local zones, serves /etc/hosts, DNSSEC validation, fast,
monitoring, Lua
Knot master/slave, AXFR/IXFR, RFC 2136, addzone, reconfiguration, DNSSEC signing,
RRL
Knot DNS Resolver DNSSEC, NTA, Lua, RFC 5011, {memcached|Redis}-backed
cache, Graphite, etcd
Yadifa authoritative, DNSSEC, RFC 2136
"I had ___, now ___, and it doesn't work" why
did you break it?

It's not always a fscking DNS problem.
dnssexy.net dig it!
