Nameserver help

[Subhash]

For most webhosts they atleat provide 2 nameservers. But my question is that is it necessay to use two nameservers while configuring the domain? What is the advantage of using all nameservers where only one can do the work.

If one goes down another one can quickly and easly take its place without notice to anyone.

Use 2 minimum, more are a bit of a benefit as propogation can be a bit quicker on changes.
