The IP Services Volume is organized as follows: 

IP Address 

An IP address is a 32-bit address allocated to a network interface on a device 
that is attached to the Internet. This document introduces the commands for IP 
address configuration. 

ARP 

Address Resolution Protocol (ARP) is used to resolve an IP address into a data 
link layer address. This document introduces the commands for ARP, 
Gratuitous ARP, Proxy ARP and Local Proxy ARP, and ARP Attack Defense 
configuration. 

DHCP 

DHCP is built on a client-server model, in which the client sends a configuration 
request and then the server returns a reply to send configuration parameters 
such as an IP address to the client. This document introduces the commands 
for DHCP server configuration, DHCP relay agent configuration, DHCP Client 
configuration, and DHCP Snooping configuration. 

DNS 

Used in the TCP/IP application, Domain Name System (DNS) is a distributed 
database which provides the translation between domain name and the IP 
address. This document introduces the commands for DNS Client and DNS 
Proxy configuration. 

IP Performance 

In some network environments, you need to adjust the IP parameters to 
achieve best network performance. This document introduces the commands 
for Enabling Reception and Forwarding of Directed Broadcasts to a Directly 
Connected Network, TCP Attributes and ICMP to Send Error Packets 
configuration. 

UDP Helper 

UDP Helper functions as a relay agent that converts UDP broadcast packets 
into unicast packets and forwards them to a specified server. This document 
introduces the commands for UDP Helper configuration. 

URPF  

Unicast Reverse Path Forwarding (URPF) protects a network against source 
address spoofing attacks. This document introduces the commands for URPF 
configuration.
