ISC DHCP 3.1-ESV is End-of-Life on March 1st, 2012

26 Jan 2012

ISC DHCP 3.0 was first released in 2007 and has lived a good long life. ISC has extended the End-of-Life (EOL) date by over six months and is now officially announcing ending support on March 1st, 2012 for ISC DHCP 3.1-ESV (Extended Support Version), there will not be any further bug or security fixes after this date. This was the last supported version of the  DHCP 3 family of software releases. The currently supported versions of the software are available on our DHCP versions page.

ISC DHCP version 4 offers several advantages over version 3, including:

  • IPv6 support
  • performance improvements for busy servers
  • improved failover protocol
  • support for more host operating systems
  • code updated for compliance with modern compilers
  • Support for the rapid-commit option on the client side
  • Prefix Delegation support
  • many security fixes, bug fixes, and other feature improvements

If your organization requires a long time to upgrade, our recommendation is to move to ISC's current Extended Support Version (ESV) ISC DHCP 4.1-ESV-R4.  It will be stable and patched only for significant and applicable bug fixes until December 2014.  No new features will be back-ported to any ESV release. Read more about our ESV, EOL and software support policy.

Here is an Article in our new KnowledgeBase containing migration considerations when upgrading from DHCPv3 to DHCPv4.
