 OpenStreetMap DNS
 ======================================
 
-This repository contains the DNS zonefiles and related code for managing OpenStreetMap.org and other domains. A full list of the managed domains available in [Makefile](Makefile).
-
-The authoritative DNS nameservers we use are kindly run by [Bytemark](https://docs.bytemark.co.uk/article/content-dns/). We would like to thank [Bytemark](https://www.bytemark.co.uk/) for their many years of support.
+This repository contains the DNS zone templates and related code for managing OpenStreetMap.org and other domain names. The full list of domains managed by this repo are in the [dnsconfig.js](dnsconfig.js) file.
 
 ## Standard DNS Zone Files
 
-The [zone files](src/) are templated [tinydns-data](http://cr.yp.to/djbdns/tinydns-data.html) syntax and are written out by the [Makefile](Makefile).
+We use [dnscontrol](https://stackexchange.github.io/dnscontrol/) to manage OpenStreetMap DNS. A set of wrapper scripts are used, which are called from the [Makefile](Makefile)
 
-On commit of a DNS update, a git [post-receive](https://github.com/openstreetmap/chef/blob/master/cookbooks/dns/files/default/post-receive) runs `make update` via a [script](https://github.com/openstreetmap/chef/blob/master/cookbooks/dns/templates/default/dns-update.erb`) which then pushes the updated zonefiles to the authoritative DNS nameservers.
+Merges to the master branch trigger a git [post-receive](https://github.com/openstreetmap/chef/blob/master/cookbooks/dns/files/default/post-receive) which runs `make update` via a [script](https://github.com/openstreetmap/chef/blob/master/cookbooks/dns/templates/default/dns-update.erb), the DNS is then updated by dnscontrol.
 
 ## GeoDNS Zones
 
-The GeoDNS zones are handled differently.
-
-### tile.openstreetmap.org (mkgeo Generated)
-
-The `tile.openstreetmap.org` and `[a|b|c].tile.openstreetmap.org` are CNAME'ed to `tile.geo.openstreetmap.org` zone.
-
-The `tile.openstreetmap.org` zone file is written by [mkgeo](bin/mkgeo) which attempts to match the [estimated country bandwidth requirements](bandwidth/tile.openstreetmap.yml) to the nearest [running](https://uptime.openstreetmap.org/) [tile cache server](src/tile.openstreetmap) with available capacity.
-
-Example `tile.openstreetmap.org` zone file snippet in [tinydns-data](http://cr.yp.to/djbdns/tinydns-data.html) syntax as generated by [mkgeo](bin/mkgeo):

-+baku.tile.openstreetmap.org:94.20.20.55:600
-```
-
-The current tile.openstreetmap.org matching is here: https://dns.openstreetmap.org/tile.openstreetmap.org.html
-
-### tile.geo.openstreetmap.org (GeoIP)
-
-The `tile.geo.openstreetmap.org` zone uses authoritative [gdnsd](https://gdnsd.org/) DNS nameservers (`a.ns.openstreetmap.org`, `b.ns.openstreetmap.org`, etc ).
-
-The gdnsd config is managed using a [chef cookbook](https://github.com/openstreetmap/chef/tree/master/cookbooks/geodns).
-
-The DNS responses from `tile.geo.openstreetmap.org` are CNAMEs to XX.tile.openstreetmap.org, where XX is the ISO 3166-1 alpha-2 country code from the [client subnet if supplied by EDNS0](https://tools.ietf.org/html/rfc7871) or the IP address of the resolving DNS if the client subnet is not supplied by EDNS0.
-
-A typical DNS query flow example: `a.tile.openstreetmap.org -> CNAME tile.geo.openstreetmap.org -> CNAME gb.tile.openstreetmap.org. -> CNAME aalborg.tile.openstreetmap.org. -> A aaa.bbb.ccc.ddd`
-
-### render.openstreetmap.org (mkgeo Generated)
-
-The `render.openstreetmap.org` zone is a DNS zone used internally by the tile.openstreetmap.org cache servers and ***SHOULD NOT BE BE USED BY OTHERS***.
-
-The `render.openstreetmap.org` zone file is written by [mkgeo](bin/mkgeo) which attempts to match the estimated caches' bandwidth requirement (dynamically generated above tile.openstreetmap.org mkgeo) to the nearest [running](https://uptime.openstreetmap.org/) [render server](src/render.openstreetmap) with available capacity.

+For GeoDNS zones we use [gdnsd](https://gdnsd.org/) with gdnsd config files generated by scripts called from the [Makefile](Makefile) file.
