You may leave out fields that do not\napply to your community (e.g. `asn`, `domains` and `nameservers`).\n\nStick to one file per community. The filename must match your communityname\non the [freifunk-api](https://github.com/freifunk/api.freifunk.net).\nYou may add stub DNS zones (e.g. dn42, rzl, hack) by leaving out\neverything but `domains` and `nameservers`.\n\nScripts for the automatic configuration generation and provisioning of various services (bird, bind, dnsmasq,\n...) are kept in a separate repository: [icvpn-scripts](https://github.com/freifunk/icvpn-scripts)\n\nNotes on IPv4 allocations\n-------------------------\n\n* There is only a limited amount of usuable IPv4 space available.\n* 10/8 is used for connections between community networks across the ICVPN.\n* Previously, people just took a /16, which means space is exhausted after 255 communites picked a network.\n* Thus: think before you allocate a v4 network here: do you really *need* IPv4 connectivity between your and other Freifunk networks? If not, consider to use IPs from 172.16.0.0/12 or 198.18.0.0/15 internally and do NOT announce them to ICVPN.\n* If you think you do, please be conservative; rule of thumb: Meshes might not size well beyond 2000 concurrent users, double that for decent DHCP timings =\u003e a /20 (4k IPs) per Mesh sounds reasonable. For additional systems outside the Mesh, an additional /22 (1024 IPv4 addresses) might be sufficient.\n* If you use mostly routing (OLSR), things might look different, you might look into e. g. an /21 to distribute to clients and another /22 for p2p-links if needed.\n* Again, please plan ahead, than take your pick. Be prepared to be questioned on why, if you took e. g. more than /18 directly. But remember as well, that renumbering IS a pain.\n* If you need more than a /18 in one community or city you need a _very_ good explaination, why you do need it.\n* Minimum net size is /22, round up if you need less.\n\nExample\n-------\n\n```\n  # This is your ASN.\n  asn: 65052\n\n  # A list of people to contact in case of technical emergency.\n  # Automated monitoring systems might use this.\n  tech-c:\n    - nils@nilsschneider.net\n    - mschiffer@universe-factory.net\n  \n  # Prefixes announced by your AS.
