You can do a rDNS-like lookup at routeviews.org, e.g., $ host -t txt 1.1.89.167.asn.routeviews.org 1.1.89.167.asn.routeviews.org descriptive text "11377" "167.89.0.0" "18" R's, John _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
