Again, I do not know what m/c is.

Also,is there any other case in which SSH host key Fingerprint gets changed.It would be very helpful to me.

Not aware of any. It should not change at all in general. Note that while admin can change it, he/she should not do this.

Thanks Martin,

Do not know what M/c is.

Yes, admin can do anything.

IP change does not have host key. But it can invalidate hostkey cache on client side. Though WinSCP .NET assembly does not have a cache.
