#464 (closed) size limit for incoming zone transfer

  • max-zone-size option is part of zone/template
  • zone size is measured in uncompressed wire format

currently only IXFR and AXFR is used this limit, IXFR, AXFR and DDNS is limited.

Question: Should we limit zone size at all inputs to the server (file, ctl, ) ?

IXFR:

Counting size of incoming add and delete sections. Transfer fail when:

  1. Actual zone size + add size - delete size > limit
  2. add size + delete size > 2 * limit
  3. size of new created zone > limit
