For some environments, especially smaller ones where network changes are somewhat infrequent, this may not be a big deal.
It only takes a few minutes, and may save you from a headache or two down the road.
In a typical environment, it’s common to see a network configured where a dynamic record can be registered by a client itself, or by the DHCP server(s) on behalf of a client.
In most cases, as long as the device is powered on and connected to your network, this registration process will occur roughly every 24 hours, keeping the dynamic record fresh and active in DNS.
From time to time, we admins will set up static records.
In this part we are going to talk about configuring high availability for DHCP.
