INEX operates an AS112 service that is used by most Irish ISPs which
ensures lookups for these ranges should always be null-answered quickly.

See: https://www.inex.ie/technical/as112


The following command will show you which AS112 service answers for you:

dig @prisoner.iana.org hostname.as112.net any
