By default, the valid leasing period of IP address is 1 day.

6Configure the IP Address of Egress Gateway Router for DHCP Clients

When a DHCP client accesses a server (or host) beyond the local subnetwork, all the data must be sent and received via the egress gateway for the local network. Only a maximum of 8 egress gateway addresses can be configured in each DHCP address pool.

Perform the following configurations in DHCP address pool view.

Table 372 Configure the gateway router address of client

Operation	Command
Configure the egress gateway address of DHCP	gateway-list ipaddress1 [
client	ipaddress2 … ipaddress8 ]
Delete the egress gateway address of DHCP client	undo gateway-list {
	ip-address all }

By default, the egress gateway address of DHCP client is not configured.

When specifying multiple egress gateway addresses, you need to continuously configure up to two addresses in the gateway-listcommand, instead of using this command repeatedly. That is because the new egress gateway address will replace the previous one other than superimposing it.

7Configure Domain Name of DHCP Client

In DHCP servers, the domain names used by the corresponding clients can be specified respectively for each address pool.

Perform the following configurations in DHCP address pool view.

Table 373 Configure the domain names of DHCP clients

Operation	Command
Configure the domain name allocated to a DHCP client	domain-name domainame
Delete the domain name allocated to a DHCP client	undo domain-name

By default, the domain names allocated to DHCP clients are not configured.

8Configure IP Address of DNS Used by DHCP Clients

When a computer accesses the Internet through the domain name, the domain name should be resolved to IP addresses. To access the DHCP client to the Internet, a DHCP server specifies the DNS address for the client when allocating the IP address to it. Each DHCP address pool can be configured with up to a maximum of 8 DNS addresses.

Perform the following configurations in DHCP address pool view.

Table 374 Configure the DNS addresses in a DHCP address pool

Operation	Command
Configure the addresses of DNSes for the DHCP	dns-listipaddress1 [
clients	ipaddress2 … ipaddress8 ]
Delete the IP addresses of DNSes for the DHCP	undo dns-list { ip-address
clients	all }

By default, the IP address of DNS is not configured.

When specifying multiple DNS’s, you need to continuously configure up to two addresses in the dns-listcommand, instead of using this command repeatedly.
