While none of the address are listed in any "major" RBL (multihop.dsbl.org
certainly isn't), there are a few listings for both addresses (checking
122 different RBLs, ick). Here is a summary for both addresses:

bl.redhatgate.com
blackhole.compu.net
pm0-no-more.compu.net

dnsbl-3.uceprotect.net
ybl.megacity.org

=======================================================================
Address 68.142.225.207 is listed on the following DNSBLs:
