The interface and default lease apply server-wide. Each subnet can override the lease time.

Lifetimes are in seconds and apply server-wide. IPv6 clients learn their gateway from Router Advertisements, so there's no gateway field.

Import existing config

Paste a kea-dhcp4.conf or kea-dhcp6.conf It detects IPv4 vs IPv6 and switches for you. Nothing is uploaded — it stays in this page.

Apply to Kea

Apply this config to a running Kea server with no restart. Apply & save updates only the subnets you changed (via the subnet_cmds hook) and writes the file — the safest option. Full replace rewrites the entire running config; use it only if per-subnet apply isn't available. If the helper isn't running, copy the commands into a terminal instead.

Control socket path

Config file on the server

1 · Validate the new file

Run after copying the file onto the server. Exit code 0 means it's good.

2 · Apply it — reload from file

No downtime. If the file is invalid, Kea keeps the old config running.

Or push it directly, without a file

Send this exact config (into memory)

Then write it to disk, so a later reload won't lose it

These talk to Kea's UNIX socket, so run them on the Kea server (or over SSH). Keep that socket owned by Kea's own user, and never expose an HTTP control port to the network without TLS and authentication in front of it.

Config backups

A backup of the running config is saved automatically before every apply. Restore one to roll back — restoring takes a fresh backup first, so it's undoable too. Newest first; the most recent 20 per family are kept.
