Title: ISC DHCP deprecated
Post by: endurium on March 17, 2026, 04:45:35 PM
Now that ISC DHCPv4 has been deprecated to a plug-in, should I be looking to switch DHCP service on my OPNSense router?  I've looked at DNSMasq and it doesn't appear do everything I'd want, namely the ability specify a specific DNS service for a certain group of devices, for example, pointing all of my smart TV and media devices to Adguard Home or Pi-Hole. Kea seems to have all the features of ISC DHCP but much of it can't be configured via the GUI and requires diving into an SSH shell, so for now I'll continue using ISCv4 for DHCP but the question is, will OPNSense ditch it completely in the near future and if so, will Kea be updated to the degree that everything about it can be configured via the web UI?

It won't be removed until some yet undecided time after 26.7 - you are good until at least 2027.

You can accomplish that using DNSmasq by applying tags.

If you are using Pi-Hole then you probably know that FTLDNS is DNSmasqd with additional features, so a lot you can do there you can apply to DNSMasqd in OPNsense too as long as you stick to the manual page of pure DNSmasqd : https://linux.die.net/man/8/dnsmasq ;)
