Precaching in Bind 9 and up

[Broek, van den, Gijs (J.G.)]

Hi,

 

Does the resolver of Bind 9 and up use any kind of precaching of resource
records by default? For instance, does the Bind resolver requery a resource
record at an authoritative name server before the cache registry for that
particular resource record expires (i.e., at a time < TTL)? If it does so by
default, at which point in time will it perform precaching (e.g., TTL-10%)?

 

Kind regards,

 

 

Gijs van den Broek
