How would I go about setting up an A record for in Bind9 for any negative queries? I want to forward our staff to an informational page if they were to visit a non existent domain. We have an internal caching server.

    There is an article here on setting up NXDOMAIN redirects: BIND 9.9 redirect zones (for NXDOMAIN redirection).

    Here is the example as given by ISC, but full explanation is available on their page.

    In named.conf, you add a new "zone":

    zone "." {
    type redirect;
    file "db.redirect" ;
};

    And then in that zone file db.redirect, you populate it with your answer:

    $TTL 300
@ IN SOA ns.example.net hostmaster.example.net 0 0 0 0 0
@ IN NS ns.example.net
;
; NS records do not need address records in this zone as it is not in the
; normal namespace.
;
*. IN A 10.100.100.2
*. IN AAAA 2001:ffff:ffff::10.100.100.2

    Instead of *., you can narrow down TLDs and domains. For example, if you only want failed .co.uk addresses to be redirected to a specific address:

    *.CO.UK. IN A 10.100.100.4
*.CO.UK. IN AAAA 2001:ffff:ffff::10.100.100.4
