It works very well. One large country's incumbent telco has all of its subscribers behind a scripted powerdns server synthesising PTRs, and with exception of the large hardware cost savings (these were gigabyte size zones), nobody noticed. > 1) Zone transfers? > 2) Dynamic update? 1 & 2 typically don't happen in such cases. > 3) DNSSEC? This will pretty much break, unless you also teach the system how to synthesise NSEC(3).
