Superloop CGNAT: Opt-Out Steps, IP Range & Fixes (2026)
Find out if Superloop uses CGNAT, how to opt out for free or dynamic IP, check your 100.64.0.0 IP range, and fix port forwarding for gaming and hosting.
Quick answer: Superloop CGNAT status & opt-out
Yes, Superloop activates Carrier-Grade NAT (CGNAT) by default for all residential NBN and Opticomm connections to conserve IPv4 space. Under CGNAT, your router WAN IP falls within the shared 100.64.0.0/10 range, which completely breaks incoming port forwarding, causes Strict/Moderate NAT in online games, and prevents remote access to Plex, Home Assistant, and security cameras. While Superloop's website chatbot primarily steers customers to buy a paid static IP ($5/month), NBN users can often request a free dynamic public IP by calling phone support directly (1800 57 87 37) and citing remote security camera needs. If Superloop refuses free opt-out or you are on Opticomm, a port-forwarding VPN like Proton VPN (1-click NAT-PMP) or PureVPN (dedicated IP / static ports) bypasses CGNAT instantly without recurring carrier fees.
How Superloop CGNAT Breaks Ports, Hosting & Gaming
While standard web browsing and video streaming work normally, superloop cgnat acts as an upstream carrier firewall that drops unrequested incoming traffic. Identify which of these three core failure scenarios affects your connection:
Strict / Moderate NAT
PlayStation (NAT Type 3), Xbox (Strict NAT), or PC matchmaking queues fail, with broken party voice chat and inability to host lobbies in games like Call of Duty.
Broken Port Forwarding
You configure port forwarding rules on your router for Plex, Minecraft (25565), or Home Assistant, but external port checkers consistently report the port as "Closed".
Unreachable Remote Services
Security camera NVRs, Synology NAS direct links, and self-hosted WireGuard or OpenVPN tunnels become completely unreachable from outside your home Wi-Fi.
How to Verify Superloop CGNAT on Your Router in 60 Seconds
To confirm 100% whether your Superloop service is currently trapped behind carrier NAT, compare your router's internal WAN address against your public address:
Log into your home router admin interface (typically 192.168.1.1 or 192.168.20.1). Locate the Status, WAN, or Internet page. Look at the IPv4 address assigned to your connection.
CGNAT IP Range: 100.64.0.0 to 100.127.255.255
If your WAN IP starts with 100.64.x.x through 100.127.x.x, Superloop is running CGNAT on your line.
Visit natchecker.com or whatismyip. Look at your external public IP address.
IP Mismatch = Upstream Carrier NAT
If your router WAN IP (e.g. 100.64.12.34) does not match the public IP seen by the website, outside packets stop at Superloop's carrier gateway and cannot reach your router.
How to Opt Out of Superloop CGNAT (The 2026 Reality)
Reddit r/nbn experiences, verified phone scripts, and understanding NBN vs. Opticomm policies.
Superloop NBN Customers
Historically and continuing into 2026, many Superloop NBN customers report successfully obtaining a free dynamic public IPv4 address by contacting support directly. However, Superloop has gradually tightened policy: the web chatbot will almost always claim opt-out is impossible without buying a static IP. Calling phone support directly with a legitimate technical justification remains the most effective method.
Superloop Opticomm Customers
If your home connection is delivered via Opticomm private fiber rather than NBN, Reddit community reports indicate that Superloop support almost universally refuses free CGNAT removal. Opticomm infrastructure routing typically requires customers to either purchase the $5/month static IP add-on or use a port-forwarding VPN to route around the restriction.
The Proven Phone Support Script (Skip the Chatbot)
Do not waste time with Superloop's automated web assistant, which is scripted to upsell add-ons. Call 1800 57 87 37 during Australian business hours (8:00 AM – 6:00 PM AEST) and use this verified script:
Hi, I am calling regarding my Superloop broadband account. I need to opt out of Carrier-Grade NAT (CGNAT) and have my connection placed on an unshared dynamic public IPv4 address. I have a security camera NVR system and a home office VPN that require direct inbound connections, which are currently failing behind the 100.64.x.x carrier NAT pool. Please remove CGNAT from my service profile.
Pro Tip from Reddit: If the tier-1 support agent insists that you must purchase a static IP, politely ask them to verify with tier-2 network engineering whether a dynamic public pool is available for your NBN POI. Many customers report approval once escalated.
Critical Step: Release the DHCP Lease After Approval
Once customer service applies the change to your profile, your router will not automatically switch to a public IP while holding its existing carrier lease. Follow these steps:
- Power off your NBN NTD (the white fiber or HFC box on the wall).
- Power off your router.
- Wait 15 to 20 minutes to allow Superloop's BNG (Broadband Network Gateway) to expire your previous CGNAT DHCP lease.
- Power on the NBN NTD first and wait for all lights (Power, Optical, LAN) to turn solid green.
- Power on your router, log into its status page, and confirm your WAN IPv4 no longer begins with 100.64.x.x.
Does Superloop IPv6 Solve CGNAT Port Forwarding?
Superloop provides native dual-stack IPv6 with dynamic /56 prefix delegation on supported routers. Because IPv6 addresses are globally unique, there is no CGNAT on IPv6.
However, IPv6 does not solve incoming IPv4 traffic. If you host a game server (such as Minecraft or Assetto Corsa), or stream to friends over mobile networks that lack IPv6 routing, their devices cannot connect to an IPv6-only host. Major gaming consoles (like Nintendo Switch and PlayStation 4/5) also rely heavily on IPv4 peer-to-peer matchmaking, meaning IPv6 alone will not eliminate Strict NAT warnings.
Why Pay Superloop $60/Year When a Port-Forwarding VPN Gives You More for Less?
Superloop charges $5 AUD per month ($60 AUD per year) for a static IPv4 add-on. If you stay on the plan for three years, that is $180 spent solely on an unencrypted, bare public IP that leaves your web traffic completely exposed to Australia's mandatory telecommunications data retention laws.
A premium port-forwarding VPN solves your CGNAT inbound reachability, restores Open NAT for gaming, and provides military-grade encryption for all your home devices at a fraction of the cost.
| Solution | Annual Cost | CGNAT Bypass | Privacy & Retention | Port Capability | Overall Verdict |
|---|---|---|---|---|---|
| Superloop Paid Static IP ($5/mo) | $60.00 AUD / year | Yes (Direct public IPv4) | None (All traffic logged under Australian metadata laws) | All 65,535 ports open on router | Expensive recurring fee for zero privacy benefits |
| Superloop Free Dynamic Opt-Out (Phone) | $0.00 AUD / year | Yes (If approved on NBN) | None (ISP logs all session metadata) | Standard router port forwarding | Best free fix if you are on NBN and support approves it |
| Proton VPN (1-Click Port Forwarding) | Significantly lower on multi-year plans | Yes (Encrypted tunnel bypass) | Maximum (Audited no-logs, Swiss jurisdiction) | Automated 1-click dynamic port (NAT-PMP) | Top choice for torrenting, gaming NAT, and privacy |
| PureVPN (Static Ports / Dedicated IP) | Significantly lower on multi-year plans | Yes (Dedicated IP & static ports) | Strong (Always-on audit, offshore jurisdiction) | Up to 15 static reserved ports | Best budget replacement for Superloop’s static IP add-on |
