# ISC DHCP End of Life Dates

ISC DHCP is no longer maintained by ISC. We announced the [final EOL in 2022](https://www.isc.org/blogs/isc-dhcp-eol/). 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.](https://www.isc.org/dhcp_migration/)

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

| Branch | Final EOL Date |
| --- | --- |
| 4.3 | July 2018 |
| 4.2.8 | Aug 2015 |
| 4.1.2-P1 | Apr 2011 * |
| 4.0.3 | 2011 |
| 3.1.3 | Mar 2010 |
| 3.1-ESV-R3 | Mar 2012 |
| 3.0.7 | Mar 2009 |
| 3.0.0-3.0.6 | Jan 2009 |
| 2.x | Nov 2004 |
| 1.x | Jun 1998 |

4.1-ESV release extended
 Although the 4.1 branch should  have reached end of support by now, we have continued to support it because it has a substantially smaller memory footprint than later versions. The older, smaller version is particularly useful in embedded environments.

                         

Archives of older (as well as current) releases are maintained at [ftp.isc.org/isc/dhcp](https://ftp.isc.org/isc/dhcp/)
