Verizon 5G Home and CGNAT: what users should verify first
5G home internet products can vary by equipment, market, and account policy. If inbound access fails, compare your router WAN IP with your public IP first and then confirm the exact service behavior with Verizon.
What to keep in mind
- The presence of a mismatch does not automatically prove all Verizon 5G Home users are behind CGNAT.
- Carrier-managed equipment and wireless service policies may influence IPv4 behavior.
- Plan differences can matter, especially between consumer and business offerings.
Verification steps
- 1.Read the WAN IP from the gateway or downstream router.
- 2.Run a browser-based public IP check and compare the values.
- 3.Confirm with Verizon whether public IPv4 access or inbound connectivity support varies by plan.

FAQ
Verizon 5G Home and CGNAT questions
Can Verizon 5G Home behavior differ by location?
Yes, it can. Wireless service behavior can vary by market, account type, equipment, and service policies, so direct verification is important.
If I see a 100.64.x.x WAN IP, what does that suggest?
That shared range is often associated with carrier-grade NAT. It is a strong sign of upstream NAT, though you should still verify the exact service policy with Verizon.
