[racktables-users] Subnetting

Hi all,

I work for a hosting provider which has a few assignments of /19 and /20 IP
blocks.
At the moment we use bloody spreadhseets to track them in blocks of /24. On
the plus side it does make it easy to further subnet down to /29's and /30's
for dedicated servers.

If we add our existing /24's to RackTables, how would we go about subnetting
them into smaller blocks? Would it be a case of deleting a whole prefix and
adding the split up chunks back in?

Cheers
Dave
