Virtual IP failover

The Traffic Server virtual IP failover feature enables Traffic Server to maintain a pool of virtual IP addresses
that it assigns to the nodes in the cluster as necessary. These virtual IP addresses are virtual only in the sense
that they are not tied to a specific machine; Traffic Server can assign them to any of its nodes. To the outside
world, these virtual IP addresses are the addresses of the Traffic Server cluster.
