mod_asn

We call for your help with the Japanese translations for project summaries. The submitted translations will be posted after simple evaluation. (Not only the translation itself is going to be checked, but we also make sure it's clear of wiki format problems. Especially problems that are related to the layout, such as line breaks and links, will be checked, so please give heed. When there appears to be a problem with the translation itself or the layout, we may not be able to post your translation. We often see problematic cases related to links. When there's going to be a line of Japanese text right after the URL, please make sure to leave a space to separate.) Also, even with projects that may already have their summaries translated, if you find an outdated translation or typographical errors, please update. Login to start translating. When you are done, you will find your name at the bottom of the summary as the translator.

You are not Logged in. If you submit this translation, your name will not show on the this project page (will be logged as "translated by an anonymous user").

mod_asn is an Apache module that uses BGP routing data to look up the autonomous system (AS) and the network prefix (subnet) which contains a given (client's) IP address. mod_asn is highly scalable. To do lookups in high-speed, it uses the PostgreSQL ip4r datatype, which is indexable with a Patricia Trie algorithm to store network prefixes. This is the most suitable algorithm, being able to search through around 250,000 existing prefixes quickly. mod_asn is usable as a standalone module, and the lookup result can be used by scripts or other Apache modules. For instance, a download redirector could base its decisions on the lookup result provided by mod_asn.
