xtAXFR |
Send the entire contents of the zone |
|
xtIXFR |
Transmits only the changed portions of a zone |
The original zone transfer mechanism (AXFR) was not an efficient means to propagate changes to a small part of a zone, as it transfers the entire zone file.
Incremental transfer (IXFR) was proposed as a more efficient mechanism, as it transfers only the changed portion(s) of a zone.
TXFRTypes is the type used to represent the TIdDNSResolver.XFRType property.
