http://issues.apache.org/bugzilla/show_bug.cgi?id=38100 Summary: HttpServletRequest.getRemoteHost() returning invalid results Product: Tomcat 5 Version: 5.5.12 Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P3 Component: Connector:Coyote AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] This issue might be related to http://issues.apache.org/bugzilla/show_bug.cgi?id=33971 What i am seeing is that at runtime, HttpServletRequest.getRemoteHost() is returning invalid results. That is, it sometimes returns unqualified hostnames (instead of an ip, which is expected if it can't get a fully-qualified hostname). Other times it returns a hostname that has absolutely nothing to do with the IP. Some examples I see in my logs: 86.125.53.140 maps to msnbot.msn.com 88.7.11.140 maps to msnbot.msn.com 210.111.94.102 maps to crawl-66-249-66-138.googlebot.com 218.190.175.145 maps to msnbot.msn.com These are all logged by the servlet being hit, with it logging: "ip " + request.getRemoteAddr() + " maps to " + request.getRemoteHost() Now, if you try looking up the hostname associated with the above IPs after the fact you will notice none of them map to the hostnames that Tomcat claims it does. I suspect that sometimes when reverse lookup fails, Tomcat retains the rDNS result from the previous lookup instead of returning the string format of the IP. This might also be a new bug introduced between 5.5.9 and 5.5.12 because I don't recall having this problem with 5.5.9.
