You are likely paying for a static IP because your ISP’s Carrier-Grade NAT (CGNAT) infrastructure requires it for public IPv4 access, or you selected a "Static IP" add-on during checkout. To stop the fee, verify if your connection actually uses CGNAT by checking for a private RFC1918 address in the 100.64.0.0/10 range, and contact support to downgrade to a dynamic IP plan if no specific service requirement exists.
Understanding the Source of the Fee
The confusion often stems from a misunderstanding of how modern ISPs handle IPv4 exhaustion. In many regions, Internet Service Providers (ISPs) have moved to Carrier-Grade NAT (CGNAT) to share a single public IPv4 address among multiple customers. When you subscribe to a Dedicated IP, you are essentially paying for an exemption from this shared pool, granting you a unique, routable public IPv4 address that is not behind the ISP's NAT gateway.
However, some billing systems automatically assign a "Static IP" package to new connections by default, assuming users want consistent outbound connectivity for hosting services. If you did not explicitly request this feature for hosting a web server, running a game server, or accessing remote desktops securely, the monthly charge is unnecessary. The key distinction is between a dynamic IP (which changes periodically but is free) and a static/dedicated IP (which remains constant and incurs a premium).
Why CGNAT Triggers This Confusion
When you are behind CGNAT, your device receives a private IP address from the ISP’s internal network. You cannot initiate inbound connections easily without port forwarding rules managed by the ISP. Some users mistakenly believe that switching to a Dedicated IP removes them from CGNAT entirely, which is true, but they may not realize they are now paying for that privilege. If your goal was simply to get out from behind CGNAT without needing a permanent public address, you might have been over-served.
Diagnosing Your Current IP Status
Before contacting support, you must confirm whether you are currently behind CGNAT and whether you possess a dedicated public IP. This diagnostic step is crucial because the solution depends entirely on your current state.
- Check Your Local Gateway: Log into your router’s administration panel. Look at the WAN or Internet status page. Note the IP address assigned to the WAN interface.
- Verify Against Private Ranges: Compare this WAN IP against known private ranges. Specifically, look for addresses starting with
100.64.x.xthrough100.127.x.x. This range is reserved specifically for CGNAT deployments by the IETF (RFC 6598). If your WAN IP falls here, you are definitely behind CGNAT. - Compare with External View: Visit a site like
whatismyipaddress.comfrom a device connected to your network. If the IP shown there matches the WAN IP on your router, you have a public IP (Dedicated or otherwise). If the external IP is different from the WAN IP, you are behind CGNAT, and the external IP belongs to the ISP’s NAT pool.
If your WAN IP is 100.64.x.x but you are paying for a Dedicated IP, there is a configuration mismatch. It is possible the ISP provisions the static route but still places you in a NAT pool due to routing errors, or more likely, you are paying for a feature you do not see reflected in your immediate network topology because the static IP is used for specific upstream routing only.
Solutions to Remove the Monthly Fee
Once you have confirmed your status, follow these steps to eliminate the unexpected charge.
1. Downgrade to Dynamic IP
If you do not host any public-facing services, you can safely switch back to a dynamic IP assignment. This will remove the monthly fee and likely place you back under CGNAT unless you qualify for a full public IPv4 allocation based on your plan tier.
- Contact your ISP’s billing or technical support department.
- Explicitly state: "I wish to cancel my Static/Dedicated IP service and revert to dynamic IP assignment."
- Ask if downgrading will immediately remove the charge from your next invoice cycle.
2. Utilize IPv6 Instead
Many modern ISPs provide native IPv6 addresses alongside IPv4. Unlike IPv4, IPv6 addresses are typically assigned statically per interface but do not incur extra fees because the address space is virtually unlimited. If you need a stable address for remote access, consider configuring your services to listen on IPv6 instead of paying for a dedicated IPv4 address.
This approach bypasses the IPv4 scarcity issue entirely. Ensure your firewall rules allow incoming traffic on IPv6 ports, and update any DNS records to include AAAA records pointing to your IPv6 address.
3. Check for Bundled Services
Occasionally, the "Dedicated IP" fee is bundled with other services, such as a fixed-price business line or a specific security suite. Review your contract details to ensure the IP isn't tied to a mandatory package. If it is, you may need to cancel the entire bundle rather than just the IP component, which could affect your overall internet speed or support level.
Alternatives for Connectivity Needs
If you were paying for the IP to solve connectivity issues, consider these alternatives before keeping the expensive subscription.
For local network access, you might use a Virtual Private Network (VPN) or a tunneling service. These tools create encrypted tunnels that bypass NAT restrictions without requiring a public IP. For example, setting up a WireGuard tunnel allows secure access to your home network from anywhere.
If you are trying to forward ports for gaming or servers, check if your ISP offers port forwarding on the CGNAT layer. Some providers allow you to reserve specific ports within their NAT pool, providing a similar experience to a dedicated IP at a lower cost or for free.

Frequently Asked Questions
Will removing the Dedicated IP put me back behind CGNAT?
Yes, if your ISP assigns IPs dynamically and has exhausted its public IPv4 pool, reverting to a dynamic IP will likely place you behind CGNAT again. However, this is common and does not affect general browsing speeds or standard usage.
Can I keep the Dedicated IP but reduce the cost?
Most ISPs do not offer partial discounts for dedicated IPs. The fee is usually a flat rate for the resource reservation. You might negotiate a lower rate only if you are threatening to cancel the entire service, but standard policy rarely allows price adjustments for individual features.
Is it safe to cancel the Dedicated IP if I run a home server?
It is risky if you rely on the static IP for consistent inbound connections. Without it, you will need to use dynamic DNS services or port forwarding protocols that work with CGNAT to maintain accessibility. Test your server's reachability after cancellation carefully.
How long does it take for the fee to disappear?
Billing cycles vary, but most ISPs apply changes within one to two billing periods. Request confirmation from support that the change takes effect immediately to avoid being charged for a full month after your request.
What if my ISP refuses to remove the Dedicated IP?
If your contract mandates a static IP for business-class tiers, you may be locked in until the term ends. In consumer plans, however, ISPs generally comply with requests to downgrade to dynamic IPs as it reduces their management overhead.
