No, an IP address does not expire in the sense of a set expiration date. However, it can change. For dynamic IP addresses, which are temporarily assigned by a network, they can change each time a device reconnects to the network. Static IP addresses, on the other hand, remain constant and are assigned by an administrator. It's crucial for users needing stable online presence, like websites, to maintain static IP addresses.
