How to set up a static IP with your ISP

Most home and even business connections use a dynamic IP — an address that changes periodically. For those who host servers, remotely access cameras, use a corporate VPN, or work in advanced remote setups, this can be a serious problem. The solution is a static IP, also called a fixed IP.

Dynamic IP vs static IP: what's the difference?

Dynamic IP is assigned automatically by your ISP every time you connect or reconnect. It may change daily, weekly, or stay the same for months — it depends on the ISP and address availability. This is the default for most home plans.

Static IP is a permanent address reserved exclusively for your connection. It doesn't change when you restart the router, and it doesn't change over time. You can always be reached at the same address on the internet.

To check your current IP and track whether it changes, visit meuip.dev regularly — if the number is different between visits, you have a dynamic IP.

Who needs a static IP?

Not everyone needs a static IP. It makes sense mainly for:

  • Home or business servers — web, FTP, email, database
  • Security cameras and DVRs accessed remotely
  • Corporate VPN that requires IP-based authentication
  • Remote access to computers and internal systems
  • Developers hosting applications locally
  • Gamers running game servers
  • Businesses that need IP allowlisting on partners' firewalls

How to request a static IP from your ISP

The process varies by provider. In general:

  1. Contact your ISP's business or technical support and ask about static IP options. It may be available as an add-on to your existing plan.
  2. Check your plan details — some ISPs include static IPs in higher-tier plans without advertising it explicitly.
  3. Ask about pricing — static IPs typically cost an additional monthly fee, ranging from a few dollars to around $10–20 depending on the provider.
  4. Confirm the configuration details — once activated, your ISP will provide the IP address, subnet mask, default gateway, and DNS servers.

Smaller regional ISPs and local fiber providers often offer static IPs more easily and at lower prices than large carriers. It's worth checking directly with your provider.

How to configure it after contracting

Once your ISP activates the static IP, configuration depends on your equipment:

On the router (manual configuration)

  1. Access the router's admin panel (usually 192.168.0.1 or 192.168.1.1 in a browser)
  2. Go to WAN or Internet
  3. Change the connection type from DHCP to Static IP
  4. Enter the details provided by your ISP:
    • IP address
    • Subnet mask
    • Default gateway
    • Primary and secondary DNS
  5. Save and restart the router

Verifying it worked

After configuring, visit meuip.dev and confirm that the displayed IP matches the address provided by your ISP. Restart the router again and check — the IP should remain the same.

Alternatives to a static IP

If getting a static IP isn't feasible (too expensive or unavailable), there are alternatives:

Dynamic DNS (DDNS) Services like No-IP, DuckDNS, and Dynu associate a domain name with your dynamic IP and update automatically when the IP changes. Free for basic use, they're sufficient for remote access to cameras and home servers.

Tunneling services Services like Cloudflare Tunnel, ngrok, and Tailscale let you expose local services to the internet without needing a static IP or opening ports on the router. Especially useful for developers.

VPS as an entry point Renting a virtual server (VPS) with a static IP and using it as a reverse proxy for your local network is an elegant technical solution for those comfortable with networking.

Security considerations

Having a static IP comes with additional security responsibilities:

  • Active firewall — with a static IP, your address is a permanent target for automated scanners
  • Keep everything updated — devices exposed to the internet must always be up to date
  • Close unused ports — only open the ports strictly necessary on the router
  • Monitoring — consider checking your IP against reputation lists periodically

Conclusion

A static IP is an essential tool for those who need reliable remote access or host their own services. The contracting process varies by ISP, but it's generally straightforward and the additional cost is justified by the benefits. For those who can't or don't want to pay for one, DDNS and tunneling alternatives handle most home use cases.

Regardless of whether you have a static or dynamic IP, keeping track of your current address is always important. meuip.dev lets you verify this instantly, at any time.
