How To Manage DHCP Scopes Running Out Of Ip Addresses? 4 Amazing Steps

In this article we will discus how to manage DHCP scopes running out of ip addresses?DHCP scope is a range of IP addresses that a device is assigned. When the number of devices in a scope increases, the administrator needs to allocate more IP addresses or the devices will not be able to communicate with each other.

Step 1: Identify The Scopes That Are Running Out Of Address Space

To identify the scopes that are running out of address space, you can use the “ip DHCP show scope” command. The output will show all of the scopes in the system and how many addresses are available for each one.

1. Allocate New Addresses To The Scopes That Are Running Out Of Address Space

To allocate new addresses to the scopes that are running out of address space, you can use the “ip DHCP assign” command. You can assign an unlimited number of addresses to a scope, but you need to be sure that there is enough room in the IP address pool for all of the devices in that scope.

2. Modify The DNS Settings For The Scopes That Are Running Out Of Address Space

If the devices in a scope are using the same DNS server, you can modify the DNS settings for that scope so that the devices will be able to find each other.

Step 2: Allocate New Addresses To The Scopes

That Are Running Out Of Address Space

If the devices in a scope are using the same DNS server, you can modify the DNS settings for that scope so that the devices will be able to find each other.

Step 3: Update The DNS Servers For Each Scope

If the devices in a scope are using different DNS servers, you will need to update the DNS servers for each scope so that the devices can find each other.

Step 4: Check For unresolvable hostnames And Clients Not Being Admitted To networks

If the devices in a scope are not being able to find each other, you may need to check the DNS settings and update the DNS Servers for each scope. You will also need to check for unresolvable hostnames and clients not being admitted to networks.
