ISC DHCP End of Life Dates

Article summary

ISC DHCP is no longer maintained by ISC. We announced the final EOL in 2022. Some operating system packagers may still distribute ISC DHCP, but we are not aware of any significant, fully-maintained forks, so we recommend users migrate to ISC's Kea DHCP server, or another DHCP server. There are some resources that may help with migration located on the ISC web site.

The table below shows when each major branch of ISC DHCP was declared End of Life.

4.1-ESV release extended

Archives of older (as well as current) releases are maintained at
