Warnings
----------------------------------------------------------------------
o The zone contains more than one authoritative name server with the
same IP address
The name servers "proxy.purenet.com.eg." and
"ns1.purenet.com.eg.", which are authoritative for
"purenet.com.eg.", have the same IP address (213.131.67.10).
o "ns1.purenet.com.eg." does not contain the latest version of the
zone
"ns1.purenet.com.eg." contains an old version of the zone. The
latest version of the zone has the serial number "93", but the
version contained at "ns1.purenet.com.eg." has the serial number
"88".
o The primary name server "ns1.purenet.com.eg." contains old data.
"ns2.purenet.com.eg." was selected as the primary server
The server "ns1.purenet.com.eg." which, according to the SOA
record, is the primary server for the zone, contains an old
version of the zone. The DNS Analyzer will use the zone data from
the server "ns2.purenet.com.eg.", which contains a later version
of the zone.
o The CNAME record "secure.purenet.com.eg." is a part of a CNAME chain
The CNAME record "secure.purenet.com.eg." points to
"proxy.purenet.com.eg.", which is also a CNAME record.
o All name servers for the zone are on the same subnet.
All name servers for the zone are on the same subnet
(213.131.67.*). If the connection to the network breaks, your
domain will become inaccessible.
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.
