I was given the task of managing an existing DNS server and have a question about zone files that I hoped someone could help with. One of our many zone files is different than the others in that it has two entries for almost every name in the zone file in the following format;
<name> IN A <IP Address>
ip-<IP address>.domain. IN A <IP Address>
If I remove the second entry then name resolution fails. Reading on zone files has not shown me why this setup is different from all of the other zone files and even entries within this zone file.
