Zoneadm is a CGI application to allow a DNS
hosting site to delegate simple zone change
privileges to remote users via a web interface. It
allows a remote user the ability to make A, CNAME,
PTR, and MX record changes to a zone that the
DNS site administrator has given them permission to
modify. It does some sanity checking on the
information entered by the user, but it may not be
foolproof and assumes some knowledge of DNS
resource records by the users.
