Don't do that.  It was a deliberate design decision to use names
rather than IP addesses in NS records.  This allows the operators
of the nameservers to change their addresses when they need to.

B.T.W. we have the technology to automatically update delegations
if we need to and have for the last 10 years.  People just need to
stop being scared about doing it.
