Multiple records may be defined for the same hostname and all IP addresses will be returned in the result. This can be used to supply both an IPv4 (A) and IPv6 (AAAA) result for a single hostname.
Do not use DNS override functionality as the only means of blocking access to sites. There are countless ways to get around this. It will stop non-technical users, but it is easy to circumvent for those with more technical aptitude.
This field defines the hostname portion of the DNS override record (without the domain), e.g.
This may be left blank to make an override record for the domain itself, similar to an
