@JerryMouse@infosec.place @JerryMouse@infosec.exchange @mypdns @Alonely0 @floppy_bv no, I mean #IXFR. That is incremental zone transfer. #Bind9 can do it, not sure #Unbound has that too. Allows to just receiving changes compared to previous version, but need to store journal containing each change at primary and secondary server. Using AXFR is similar to downloading hosts file over http. I think PiHole uses own modified dnsmasq build, which provides webui integration.
