One bad packet can DoS a DNSSEC server

This may not effect IPFire.

Add bind9 server to IPFire system?

Both above are true. unbound is used as the DNS server on IPFire. bind is also installed but only used to provide the utilities dig host nslookup nsupdate and the libraries libbind9 libdns libirs libisc libisccc libisccfg libns for those applications used in IPFire that require certain bind libraries to be linked in for their usage. bind is not used as a dns server on IPFire.
