BUNDY - authoritative DNS Server

the BUNDY project is currently in hibernation status. It is not dead, but it is also not alive either. There is currently no active development, and no security bug fixes. We do not recommend using BUNDY as a production DNS server. BUNDY, due to it’s python code, is a great tool to prototype new DNS functions. It can be used as a prototyping tool. If you have interest on working on or with BUNDY, let us know. We can wake up BUNDY from sleep any time./

BUNDY provides an authoritative DNS server (with in-memory and SQLite3 backends), DNSSEC support, dynamic DNS, zone transfers. Supplementary components are included for statistics collection and reporting and remote configuration and control are included, as is an experimental recursive nameserver with support for forwarding. It is the continuation of the BIND 10 project from the ISC hosted at

Since the June 2013 1.1.0 BIND 10 release, the new DNS highlights include incoming zone transfer statistics, support for CAA and TLSA resource records, and the zone loader now supports the zone file $GENERATE directive. Note that the bundy-xfrin “use_ixfr” configuration item is deprecated and a new configuration “zones/request_ixfr” may be used to replace it. Also use “database_file” under the “data_sources” module for bundy-xfrin inbound transfers and use bundy-loadzone -e option to create an empty zone prior to the first transfer.

The suite also provides DHCPv4 and DHCPv6 servers, a dynamic DNS component, a DHCP performance testing program, and a C++ library for DHCP. ISC is continuing with the development of these components in a new project, Kea.

For information about the Kea project, please visit If you have any questions or comments about working with the DHCP code, you may post them to the Kea DHCP Mailing List

For the full commit history, please see the ChangeLog and the git Log.

Installation details are documented in the Guide (

The ./configure options --disable-dns and --disable-dhcp may be used to provide an optional DHCP- or DNS-only build and installation.

Bundy was a sponsored development project (under the name BIND 10) from April 2009 to April 2014, and would not be possible without the generous support of the past sponsors: AFNIC, Afilias, CIRA, CNNIC, CZ.NIC, DENIC eG, Google, IIS.SE, JPRS, Nominet, .nz Registry Services, RIPE NCC,, SIDN, and Technical Center of Internet. Support for the new DHCPv4 and DHCPv6 components is provided by Comcast.

You can’t perform that action at this time.
