CDN nodes name resolution

By default, a CDN node uses IP addresses to connect to another nodes and does not resolves their names to IPs


Nodes name resolution to IP addresses may be enabled if needed


In this case:

  • a CDN node will always try to get a name of another node by address and to get addrees by name
  • CDN nodes names will be used to establish signaling connections and to display nodes statistics

The cdn_nodes_resolve_ip parameter value must be the same for all the CDN nodes.


On every CDN node, a reverse DNS lookup must return the same another node name as forward DNS lookup for the node address if cdn_nodes_resolve_ip=true is enabled. For example, if the name is resolved to, but this address reverse DNS lookup returns, then all the requests to establish a WebRTC connection from this node will be rejected.
