DynDNS

Dynamic DNS records can be used for assigning hostnames to local devices.

It combines DHCPv4 server leases with IP neigh and add ALL device addresses to DNS hostnames.

Can be used for assinging RA addresses to device hostnames, which are defaultly NOT assigned in OpenWrt.

Add this script to dnsmasq's dhcp-script option:

dhcp-script = lua /path/to/dyndns.lua

Or via dhcpscript in uci:

config dnsmasq
	option dhcpscript 'lua /path/to/dyndns.lua'

Also add list addnhosts '/tmp/dyndns' to make dnsmasq using DynDNS's hosts file.
