Inherited DNS

[Edmiston, Jerry]

Recently, I inherited the DNS responsibilities here at work. I've worked
with DNS before and am familar with the structure and purpose of DNS. But
some things in this DNS environement are very confusing. Why would a printer
be defined to DNS? Why would multiple A records with the same IP number be
assigned to multiple host names? Why would just about every A record entry
(and there are alot) have an MX record? To me these are errors and should be
corrected. No one will admit to the entries, only pointing to people that
have long gone, but they keep insisting that they are needed. Anyway, am I
missing something or is this truly a cluster of DNS errors. Any help would
be grealy appreciated. Thanks in advance...
