- There isn't an equivalent for TCP/IP but...

- MultiNet V3.1 lets you assign a "cluster-wide" IP address. One node
- will answer to this at any one time, and if that node crashes another
- will resume answering. This only works correctly for connectionless
- protocols like NFS (not TCP) and only provides redundency, not load
- balancing.
-
- The next release of MultiNet will let you specify a cluster-wide
- NAME which the nameserver will answer with different IP addresses
- in a load-balancing fashion; this would be a little closer to
- DECnet cluster aliases.
