I'm looking for a ressource for country ip ranges that meet the following criteria:

  • free
  • accurate
  • up to date
  • updated regularly
  • has existed for some significant time and can therefore be judged to remain available for the forseeable future
  • contains IPv4 and IPv6
  • CIDR format
  • allows automated access (e.g. to keep my server up to date through a cronjob)

Nice to have:

  • open source / community effort

There are many free ressources available, but I find it hard to judge their quality, and often they aren't up to date. The most reliable ressource seem to by paid. So I wonder if there is some "open source" community effort to provide this information.
