www.dnsstuff.com says don't use: > BLARSBL, FIVETENIGNORE, FIVETENSRC, JAMMDNSBL, SPAMBAG, SPEWS > (these block large IP ranges) > MAPS-DUL, SORBS-DUHL > (these knowingly list IPs that do not meet listing criteria). I inherited some IP space listed at five-ten and blars, but nowhere else. Anyone using them?
