Hi everyone,

On ASA when we config DHCP pool then why we need to use the command

dhcpd update dns interface

Thanks

Hello Mahesh,

I have seen it on enviroments where DDNS will be run,

As you might now DDNS is the protocol that will allow you to find or determine what the IP address of a host is whether it has changed or not ( This based on it's domain name)

So there are going to be times where the mapping from IP to name and name to IP will change and clients might want to update this, If we want the ASA to honor those changes we add:

dhcpd update dns
