This software is an Apache module designed to perform look up routing data. It can be used to retrieve information related to routing and provide accurate results.
One of the key features of mod_asn is that it utilizes the PostgreSQL ip4r datatype to store network prefixes. This algorithm is indexable with a Patricia Trie algorithm, which allows you to search through the approximately 250,000 existing prefixes with ease. Furthermore, mod_asn can be used both as a standalone module and alongside other Apache modules. Its lookup result is accessible to scripts and other modules, meaning you can customize the settings depending on your preferences.
One practical application of mod_asn is on download redirectors. By basing the decisions on the lookup provided by mod_asn, download redirectors can redirect downloads to the nearest (network-wise) mirror server. For instance, a download redirector can rely on mod_asn to identify the nearest mirror server, ensuring that users get faster download speeds.
Lastly, it's worth noting that mod_asn has already been configured on Metalink generator and download redirector tools like MirrorBrain. The module is licensed under Apache License Version 2.0, which is flexible to modify or distribute. Therefore, if you're looking for a versatile Apache module that can deliver fast and reliable IP address lookups, mod_asn is an excellent pick.
