Hostname Option Support for DHCP Clients
Send the hostname of a DHCP client interface to the DHCP
server, which can register the hostname with the DNS server. The
DNS server can automatically manage hostname-to-dynamic IP address
resolutions.
When a firewall interface is a DHCP client
that is assigned a dynamic IPv4 address by a DHCP server, the changing
IP address makes it difficult for external hosts to identify the
interface. You can now assign a hostname to a DHCP client interface
on the firewall and send that hostname (Option 12) to a DHCP server,
which can register the hostname with the DNS server. The DNS server
can automatically manage hostname-to-dynamic IP address resolutions.
- SelectSend Hostnameand accept the firewall hostname (the default) or enter a unique hostname for the interface.
