I’ve worked to develop an IP Information and DNS Lookup tool to replace some other commercial products that offer similar functionality. Currently, the tool displays IP Information (including AS Number, AS Name, BGP Prefix and Allocation Date), as well as IP Information from DNS, IP Geolocation, Spam Blacklist lookup (DNSBL/RBL Lookup) and DNS Queries for A, MX, PTR and NS records. More information about the site, including example lookups can be found here: http://ipxer.com/about/
The site can be found here: ipxer.com
