The NLNOG Foundation supported by RIPE NCC commissioned a complete rewrite of IRR Explorer: https://github.com/dashcare/irrexplorer
This v1 repository has been archived.
IRR Explorer was written to make it easier to debug data in the IRR system. An example is to verify whether you would be impacted by deployment if filtering strategies such as "IRR Lockdown".

Copy irrexplorer_config.yml.dist to irrexplorer_config.yml and edit it to your liking.
Note that mirroring of many IRR databases is not possible without getting access granted.
( cd db ; ./bootstrap )
This will download IRR database snapshots and setup the database. It will take some time.
Continously updating BGP and IRR sources:
./worker
Finally start the web interface
./irexwww
There is query tool as well:
./query 1.2.3.0/24
It is rather basic and need some work though.
