Analysis examples

The following examples illustrate common output for DNS Analyzer and a short description of the output.

Example 1

The root name server is GTLD. The additional name servers are ns1.msft.net, ns3.msft.net, ns5.msft.net, ns4.msft.net, ns2.msft.net. All name servers point to one authoritative server. Msn.com does not have any DNS issues.

Example 2

The root name server is GTLD. The additional name servers are ns1.msft.net, ns3.msft.net, ns4.msft.net, and ns2.msft.net. All name servers point the authoritative servers. In this example, the DNS is hosted from eight different servers.

Example 3

There are 14 root name servers listed and 22 name servers. A non-authoritative address is found and an alias. The address is non-authoritative as it comes from the cache of the name server.

Example 4

In this example, there is an error reported from one of the Name Servers. This represents a time out issue.
