ddns-update-style. The DHCP server can be configured to update the information in the DNS server when the server issues an IP address to a client. Setting this to none disables this feature.
default-lease-time. The DHCP server issues IP addresses to the clients with a certain lifetime in seconds (14400 seconds equals 4 hours). Toward the end of this lifetime, the clients connect to the server again to renew the current IP address or to get a new one.
max-lease-time. The DHCP client can request a lifetime when it requests an IP address. The value of max-lease-time (in seconds) defines the maximum the server grants, even if the client requests a longer lifetime for the IP address.
option domain-name. The domain name of the clients served by this DHCP server.
option domain-name-servers. The IP address of the DNS server the client should use for name resolution.
option routers. The default gateway for the clients within the network
subnet. This describes the network topology. The range specifies which IP addresses will be assigned to the clients. You can specify options specific for this subnet that would override options set above this subnet declaration.
