17.5. Advanced Features of BIND
Most BIND implementations only use named to provide name resolution services or to act as an authority for a particular domain or sub-domain. However, BIND version 9 has a number of advanced features that allow for a more secure and efficient DNS service.
Some of these advanced features, such as DNSSEC, TSIG, and IXFR (which are defined in the following section), should only be used in network environments with nameservers that support the features. If the network environment includes non-BIND or older BIND nameservers, verify that each advanced feature is supported before attempting to use it.
All of the features mentioned are discussed in greater detail in the BIND 9 Administrator Reference Manual referenced in Section 17.7.1, “Installed Documentation”.
