For several reasons, the most important being that Arin limits the number of queries per day.
Second, compiling a lengthy list of IP numbers is what I am trying to avoid. ====================================== We can get rid of spam on your domain! , Anti-spam solutions http://www.clickdoug.com/mailfilter.cfm For hosting solutions http://www.clickdoug.com ====================================== ----- Original Message ----- From: "Rick Davidson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, April 28, 2004 2:15 PM Subject: Re: [IMail Forum] ANNOUNCEMENT FROM IPSWITCH - Update on 8.11 : Why not use whois.arin.net and determine their IP ranges for example, if you : want to block videotron.ca get one of their IP addresses from a spam message : then do an arin lookup on it and you would get the following info: : : Le Groupe Videotron Ltee VL-2BL (NET-24-200-0-0-1) : 24.200.0.0 - 24.203.255.255 : Videotron Ltee VL-B-BB-18C9F300 (NET-24-201-243-0-1) : 24.201.243.0 - 24.201.243.255 : : add those IP subnets to your smtp access list : : www.arin.net maintains the International IP allocations : http://www.arin.net/tools/index.html : : Rick Davidson : National Systems Manager : North American Title Group : - : ----- Original Message ----- : From: "Spaminator " <[EMAIL PROTECTED]> : To: <[EMAIL PROTECTED]> : Sent: Wednesday, April 28, 2004 2:29 PM : Subject: Re: [IMail Forum] ANNOUNCEMENT FROM IPSWITCH - Update on 8.11 : : : > I wholeheartedly agree with this request! : > : > Specific to the url-domain-bl.txt file, I'd like to be able to filter out : domains like *hosting.com.
