When the ypwhich Command Is Inconsistent

When you use the ypwhich command several times at the same client node, the response varies because the status of the NIS server changes. The status changes are normal.

The binding of NIS client to NIS server changes over time on a busy network, when the NIS servers are busy. Whenever possible, the system stabilizes so that all clients get acceptable response time from the NIS servers. The source of an NIS service is not important, because an NIS server machine often gets its own NIS services from another NIS server on the network.
