What should a network administrator do to accommodate new devices when all IP addresses are allocated?

When a network administrator faces a situation where all IP addresses have been allocated, the most appropriate action to take is to increase the size of the DHCP scope for the network segment. This option allows the administrator to allocate additional IP addresses within the designated range, making room for new devices that need network connectivity.

Increasing the DHCP scope essentially expands the pool of available IP addresses, thereby facilitating the accommodation of new devices without requiring significant changes to the existing network infrastructure. This can be particularly useful for environments experiencing growth or temporary surges in the number of devices, such as in a corporate setting or during specific events.

Alternatively, while creating a new DHCP scope for the network segment may seem viable, it typically involves managing multiple scopes which can complicate the DHCP configuration. Configuring the DHCP server for IPv6 may be relevant in the long-term as networks transition to the newer IP protocol; however, it does not directly address the immediate need when the existing pool is exhausted. NAT (Network Address Translation) is a technique used to conserve IP addresses and translate private IP addresses to a public IP address, but it does not solve the problem of insufficient IP addresses within a DHCP scope for local devices. Thus, increasing the size of the DHCP scope is the most logical and
