DHCP

Dynamic Host Configuration Protocol (DHCP) dynamically manages and configures the
users in a centralize way. It adopts client/server communications mode. A client applies to
a server for configuration information (including parameters such as IP address, subnet
mask and default gateway), and the server returns the information according to the policy.
DHCP uses UDP as transport protocol. The host sends a message to port 67 of DHCP
server, and the server returns a message to port 68 of the host.
ZXR10 ZSR V2 supports DHCP Relay, and DHCP Server to accommodate user demands
for DHCP in different scenarios.

DNS

Domain Name System (DNS), a distributed database for TCP/IP applications, copes with

ZXR10 ZSR V2 can work as a DNS client. It sends a DNS resolution request to a DNS
server to request and receive the response message of the DNS server packet, and then
sends the message to the user.
