This help section describes the Sender Domain Validation test Invalidated IP Addresses list.
The DNS A record which resolves to any of the IP addresses listed on this list will be treated as non-existent record in the Sender Domain Validation test. Use this list to ignore global DNS A wildcards for a TLD or gTLD.
The list contains the IP address 64.94.110.11 by default. Verisign has added this global DNS A RR wildcard previously, but due to the pressure of the Internet users, they removed the wildcard.

IP addresses and IP address ranges can be edited using the IP Address List Editor dialog. The editor allows entering single IP addresses or IP address ranges which can be specified by subnet masks.
