DHCP
DHCP Overview
- A protocol that allows end stations to request IP configuration information from a local sever rather than having to be manually configured.
- DHCP can provide several pieces of IP configuration data to the end station, including IP address, IP gateway address, and addresses for IP services, such as DNS servers and WINS servers.
- DHCP advantages:
- It centralizes management of IP addresses
- Available address space is used efficiently
- DHCP also means less configuration needs to be done on individual end stations
DHCP on vRouter
For DHCP server functionality, the vRouter has two options:
- DHCP server. A basic DHCP server setup consists of an address pool, with specific parameters associated with each address pool, including the start and end addresses for the pool, the default router, the address of the DNS server, and other optional parameters.
- DHCP relay agent. If you have a central DHCP server on a different network segment than your end stations, you can configure the vRouter to forward DHCP requests to hat server.

DNS
A vRouter participates in DNS services in one of three ways.
- System DNS, the vRouter acts as a DNS client and needs to resolve host names for its own operations.
- You can configure a static system DNS server, or the vRouter can acquire the address of its DNS server using DHCP.
- Dynamic DNS is used when upstream devices use names to reach an address associated with the vRouter, but the address is assigned via DHCP.
- DNS forwarding. In this case, downstream end stations need to reach DNS services on the Internet. This scenario is common in environments where the vRouter acquires its public addressing and DNS server address via DHCP
