What testpoints are in the SURBL data?
Previously, each SURBL zone file, including the bitmask-combined list multi.surbl.org, had testpoints with A records resolving to 127.0.0.2. As of about November 2005 multi has testpoints corresponding to all ones set for each bitmask position. So testpoints for multi.surbl.org now have an A record value of 127.0.0.126 instead of 127.0.0.2 . (If a new list is added in future using the 128th bit, then the new testpoint values in multi will be 127.0.0.254 . Following tradition, the first bit is not used.) This may work better with applications that decode the bits into individual list results, but it is a change from before and it may break other applications’ use of the testpoints. The multi.surbl.org BIND zone file contains: test.surbl.org 604800 IN A 127.0.0.126 604800 IN TXT “multi.surbl.org permanent test point” test.multi.surbl.org 604800 IN A 127.0.0.126 604800 IN TXT “multi.surbl.org permanent test point” surbl-org-permanent-test-point.com 604800 IN A 127.0.0.126 604800 IN TXT “m
