Why are static IP addresses needed?

Static IP addresses are needed for devices or services that require a constant and unchanging network address. This is necessary, for example, for:

• Servers (web, mail, databases) so that clients can always connect to them using the same address.
• Firewall and router configurations, where rules are tied to specific IPs.
• Remote access and VPNs, where a fixed address is required for authentication.
• Network devices such as printers or cameras, to avoid issues with address changes upon reboot.

Thus, a static IP ensures stability and predictability in network interactions.
