I have 2 linux servers on a home network that are configured as DHCP servers in a failover configuration. They also both have named (bind9) installed.
I also want each DHCP server to use DDNS so that they update the local domain with client records.
What I'm confused about is how I should set up DNS on each server with this configuration?
So supposing my local domain is called "home.lan" which allows dynamic updates from the DHCP server. Should each DNS server be a master for home.lan? Or should the primary DHCP server be a master for home.lan and the secondary DHCP server be a slave?
How can I ensure than when clients do a reverse lookups for IP's on the lan they always get the correct answer?
