DHCP Address Pools

Use the Configuration > Services > DHCP Server page to configure a pool of DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  addresses. The managed device can use one of the addresses from this pool for its own IP address, and/or assign addresses in the pool to clients associating to that node.

It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. server.

Reserving IP Addresses

ArubaOS now allows you to manually reserve IP addresses from a DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  pool for specific devices or MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. addresses across a large number of sites. By default, managed devices dynamically lease IP addresses from a DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  pool to their connected clients. As IP addresses are randomly assigned to clients, the client devices may not acquire the same IP address every time they request for a network connection.

If your site has client devices, such as printers and scanners, for which you want to assign a static IP address, you can use IP reservation to manually bind IP addresses from a DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  pool to a client MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address. With IP reservation, managed devices can assign the same IP address to a client whenever it requests for a network connection.

The following procedure reserves an IP address from the DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  pool:

1. In the Managed Network node hierarchy, navigate to Configuration > Services > DHCP.
2. Expand the DHCP Server accordion.
3. Click + below the IP Reservations table.

   The Add Clients window is displayed.

4. Specify the Client Name, MAC Address, and the IP Address that you want to reserve.

   The Add Clients window allows five entries by default. Click + to add another row. You can configure up to 64 clients.

   Ensure that you enter a valid IP address. The IP address cannot be a broadcast (255.255.255.255), multicast (224.0.0.0/8), or loopback (127.0.0.1) address.

5. Click Submit.

   To delete a client, select the client in the IP Reservations table and click the delete icon..
