All current Netquery editions are fully compliant with W3C XHTML 1.1 standards. (Validation at that level is contingent on CMS versioning and other external environment factors.) The Netquery v3.3 complete package download also includes updated GeoIP data based on MaxMind's latest (2006-01-01) free CSV release adapted and optimized for Netquery's SQL database operations. Netquery now requires PHP version 4.1 or later and it is fully compatible with PHP 5.0 and 5.1 defaults. If upgrading, please replace all existing files. Netquery's major features currently include the following: - client "sniffer" with GeoIP option, - multidomain & IP/AS whois lookups, - autodiscovery for whois TLD server, - DNS and Dig (ANY, SOA, NS, MX) queries, - email address format & MX validation, - port check with services lookup option, - HTTP HEAD and GET requests, - ICMP pings (local and/or remote), - traceroutes (local and/or remote), - looking glass router interrogation, - usage log & "top countries" mapping, - updateable GeoIP & ports data paks, - user inputs with admin notice & approval, - multi-instance sideblocks in CMS editions, - full W3C XHTML 1.1 & CSS compliance. The administrator can enable or disable each feature individually and can configure local execution and/or a remote server script for the ping and traceroute features. The administrator can also edit all of the data tables used by the whois, port services and looking glass features and can allow site users to submit port services and exploits information for acceptance. Optional GeoIP and ports data tables can be downloaded and installed independently of the module core.
