I think this is a case of "$ethnicity whispers".
If they have a /20 then they need to setup 16 reverse zones, one for each /24 in the /20. If they are delegating smaller blocks to others then they may need to swip the smaller block. If those blocks are between /21 and /24 inclusive this will allow for reverse delegations direct from arin to the client. If those blocks are for a /25 or longer they may want to look at RFC 2317 style delegations or allow the client to dynamically update their part of the reverse zone. Mark > Is this correct?
