What Is a Static IP Address and Does My Business Need One?

A dynamic IP address can change over time. For many everyday internet tasks this is fine because users do not need to know the address of the connection.

A static IP address stays fixed. That can be useful when another system needs to recognise your premises, allow access from a known address or connect back to equipment at the site. It should be treated as part of the technical requirement, not just as an optional extra.

Static IPs are often used for VPNs, remote desktops, remote device access, servers, CCTV systems, firewall rules, security services and whitelisted supplier platforms. Some payment, booking or cloud systems may also have specific network requirements.

For example, a business with CCTV remote viewing may need reliable remote access to the recorder or camera system. A company using a supplier portal restricted by IP address may need its office connection to appear from the same public address each time.

A common switching mistake is ordering a new broadband service without checking whether existing systems use the current static IP. If the address changes unexpectedly, VPNs, firewall rules, remote access or whitelisted applications may stop working until they are reconfigured.

Before switching, list every service that may rely on the connection address. Ask whether the new service includes static IPs, how many are available, whether they cost extra and when the address will be confirmed.

A static IP does not make a system secure by itself. It can help with controlled access, but firewalls, strong authentication, updated devices and sensible remote access policies still matter.

If a static IP is used for CCTV, servers or remote access, make sure someone is responsible for the router, firewall rules and device updates. The broadband service and the internal network should be reviewed together.
