Wikipedia:WikiProject User scripts/Scripts/RBL check

/* This script adds an "[[DNSBL|RBL]] check" link to the toolbox on IP user/talk/contribs pages.

<strong style="color: red;">Important:</strong> Some care is required in interpreting the results of this tool.  In particular, some of the RBLs shown on the results page are lists of dial-up and/or broadband user IPs, and will thus include the IPs of ''most legitimate Wikipedia editors''.  Others are combined lists that may or may not include dial-up and broadband addresses.  Being listed on such RBLs does '''not''' mean the IP is an [[WP:OP|open proxy]].  In general, before blocking or reporting an IP as a proxy based on an RBL listing, make sure you carefully read the listing criteria for the matching RBLs first.
