Title:
dnsmasq resolves xyzzy.xyzzy.xyzzy. to unknown IP
Status in dnsmasq package in Ubuntu:
Incomplete
Bug description:
[enzo@Feynman ~/Temp] host xyzzy.xyzzy.xyzzy.
xyzzy.xyzzy.xyzzy has address 54.72.52.58
Host xyzzy.xyzzy.xyzzy not found: 3(NXDOMAIN)
Host xyzzy.xyzzy.xyzzy not found: 3(NXDOMAIN)
[enzo@Feynman ~/Temp] host 54.72.52.58
58.52.72.54.in-addr.arpa domain name pointer
ec2-54-72-52-58.eu-west-1.compute.amazonaws.com.
This is unacceptable and a potential security risk!
"xyzzy.xyzzy.xyzzy." is an invalidDNS name that needs to always fail
when resolved.
