>host 23.227.197.10
10.197.227.23.in-addr.arpa domain name pointer horsezipsworld.com.

>host horsezipsworld.com
horsezipsworld.com has address 23.227.197.11
horsezipsworld.com mail is handled by 10 mail.horsezipsworld.com.

>host mail.horsezipsworld.com
mail.horsezipsworld.com has address 23.227.197.11

>host 23.227.197.11
11.197.227.23.in-addr.arpa domain name pointer horsezipsworld.com.

The above are inconsistent.  IPAddress -> Name =/= the found name -> IPAddress

>host 209.86.93.228
228.93.86.209.in-addr.arpa domain name pointer mx3.earthlink.net.

>host mx3.earthlink.net
mx3.earthlink.net has address 209.86.93.228

Thee appear to be consistent ...
