What does IP renumbering involve?

IP renumbering involves changing the IP address scheme of a network, typically due to a change in internet Service Providers (ISPs), the need to reorganize network architecture, or transitioning from one IP address range to another. This process can require updating router configurations, DNS records, and the settings of all devices on the network to ensure connectivity. It can also involve significant planning and coordination to minimize downtime and maintain service continuity. Overall, IP renumbering is crucial for efficient network management and addressing needs.
