This domain is definitely pretty screwed up. I checked it out
with the full registered version of DNS Expert Professional 1.6 (see
<http://www.menandmice.com/2000/2100_dns_expert.html>), and here's
what I got:

Warnings
----------------------------------------------------------------------
o "bertha.mysp.net." does not contain the latest version of the zone
"bertha.mysp.net." contains an old version of the zone. The
latest version of the zone has the serial number "2001020301",
but the version contained at "bertha.mysp.net." has the serial
number "82501".
o The name server "ns1.thepurist.org." does not permit zone transfers
The name server "ns1.thepurist.org." has been configured to
reject unauthorized zone transfers and the application will not
be able to use data from this server while analyzing the zone.
o Zone transfer from authoritative servers not possible
It was not possible to perform a zone transfer from any of the
authoritative name servers for the zone. This will limit the
range of tests performed for the zone.
o The Expire field in the SOA record contains an unusually low value
The value 7200 of the Expire field in the SOA record is unusually
low. The value for this field should be within the range 86400 -
3600000.
o The expire value in the SOA record is too close to the refresh value
The value of the Expire field in the SOA record (currently 7200)
should be at least three times bigger than the value of the
Refresh field (currently 3600).
o The refresh value in the SOA record is too close to the retry value
The value of the Refresh field in the SOA record (currently 3600)
should be at least three times bigger than the value of the Retry
field (currently 1800).
o The zone contains more than one A record with the address
216.253.137.36
There is more than one A record in the zone with the IP address
216.253.137.36.
o There is only one MX record in the zone
The zone contains only one MX record. This will cause mail
delivery problems if the primary mail server becomes unavailable.
For safety purposes, there should be two or more mail servers
for every zone, the extra mail servers being used as backup
(secondary) servers for the primary server.
