How does a node know how to connect to another node on Allstar Link?
Allstar link has an IP address distribution mechanism to periodically update all valid allstar link nodes. This information is automatically retrieved from a set of redundant Allstar node servers by a script which runs in the background on the Allstar link node. Additionally, each node periodically informs an Allstar registration server of its current IP address using the IAX register statement in iax.conf. In this way, all nodes in the Allstar link system are kept up to date with everyone’s latest IP address.
