- DNS Logging
- logging Statement Definition and Usage
Sample:
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
- Dynamic DNS
- Dynamic Zone - Allow-update
- Dynamic DNS update using nsupdate
Man Page:
nsupdate is used to submit Dynamic DNS Update requests as defined in RFC 2136 to a name server. This allows resource records to be added or removed from a zone without manually editing the zone file. A single update request can contain requests to add or remove more than one resource record.
- TSIG - Transaction SIGnatures
- BIND primarily supports TSIG for server to server communication.
- TSIG can also be useful for dynamic update.The nsupdate program supports TSIG via the -k and -y command line options or inline by use of the key.
- DNSSEC
- Cryptographic authentication of DNS information is possible through the DNS Security (DNSSEC-bis) extensions, defined in RFC 4033, RFC 4034, and RFC 4035.
