Hi,
DNS job
When a connection to a network node is to be initiated its DNS name is resolved
to an IP address which shows the location of the node on the network. So
network nodes are findable by name even if their locations change.
The job of the DNS is to identify a node by its name. Another job is to
maintain information about node's current location so a new connection can be
started at any time.
Why should DNS be bothered with connectivity and/or topology status?
There must be a distinct mechanism to handle mapping of node identity to
network location.
