Slave zones not updating dynamically Kw sex
The BIND documentation includes a description of the Master/Slave/(stealth slave) roles for authoritative servers.Update your BIND server zone files via nsupdate, or add ‘dynamic’ zone files via RNDC, both without restarting BIND.Catalog Zones were introduced in BIND 9.11.0 to facilitate the provisioning of zone information across a nameserver constellation.Catalog Zones are particularly useful when there are a large number of secondary servers.The master signals that updated information is available with a notify message to the slaves, and the slaves then initiate an update from the master.BIND fully supports both the AXFR (complete transfer) and IXFR (incremental transfer) methods, using the standard TSIG security mechanism between servers.
DNS pre-fetch is a technique for continuously refreshing the cached records for popular domains, reducing the time the user has to wait for a response. These features enable rate-limiting queries to authoritative systems that appear to be under attack.
For those times when you do have to restart, the ‘MAP’ zone file format can dramatically speed up re-loading a large zone file into BIND, such as on restart.
BIND supports the use of Hardware Security Modules through either a native PKCS#11 interface, or the Open SSL PKCS#11 provider.
We have started a BIND9 Significant Features matrix in our Knowledge Base that lists the major feature differences for current supported versions of An authoritative DNS server answers requests from resolvers, using information about the domain names it is authoritative for.
You can provide DNS services on the Internet by installing this software on a server and giving it information about your domain names.
