Does Brightspeed give you a public IP? (CGNAT, static IP and servers)

Short answer: Yes, per customer reports: Brightspeed fiber gets a public IPv4, not CGNAT, so port forwarding works. Brightspeed is one of the few US ISPs that leases static IPs on home service (postpaid plans): $15/mo for one address plus a $75 one-time fee, or larger blocks. IPv6 is available, and its subscriber agreement allows personal or commercial servers. We haven't found an official Brightspeed statement on CGNAT, so that part is low confidence.

Does Brightspeed use CGNAT?

Customers say no: Brightspeed fiber lines get a public IPv4. We haven't found an official Brightspeed page on it. The reports are cited on the Brightspeed ISP page. DSL lines may differ; if you're on DSL, run the check below and tell us what you see.

Static IP on Brightspeed

Brightspeed's static IP help page says postpaid High-Speed Internet subscribers can lease static IP addresses; prepaid customers can't. Prices on that page: a single address is $15 a month plus a $75 one-time charge, and blocks are $25 (/29), $40 (/28), $64 (/27) and $128 (/26) a month. Compare with other ISPs on static IP prices by US home ISP.

Terms, ports and IPv6

• Servers: allowed. Brightspeed's subscriber agreement (August 2025) says the service "may be used to host a server, personal or commercial", as long as it follows the agreement and isn't used for malicious purposes. The same agreement restricts server devices on Brightspeed's separate 4G home internet service.
• IPv6: yes. Brightspeed says to enable IPv6 on a compatible modem.
• Upload: symmetrical on fiber plans (200 Mbps to 2 Gig). DSL upload isn't listed.
• Ports 25/80/443: not verified yet. If you've tested them, send a report.

How to confirm on your line

1. Follow how to tell if you're behind CGNAT: compare the router's WAN IP with your public IP.
2. Run the checker. Its port test checks a forwarded port from outside, and the report sums up what you can host.
