# ACT Fibernet
> ACT Fibernet is AS18209 and AS24309 (CABLELITE-AS-AP). How to tell if your ACT plan is behind CGNAT and what to confirm on the bill.
This connection is `216.73.217.54` on AS16509 (Anthropic, PBC).

RDAP, in this site’s list checked 13 Oct 2026, names both [AS18209](https://ipinfo.fyi/asn/18209) and [AS24309](https://ipinfo.fyi/asn/24309) CABLELITE-AS-AP. PeeringDB lists AS18209 as Atria Convergence Technologies, the company behind ACT Fibernet. If your lookup shows either ASN, you are on that operator. You still do not know, from the ASN alone, whether your plan is behind CGNAT.

## The test

Open the [CGNAT check](https://ipinfo.fyi/tools/cgnat) from a device on the ACT router. Open the router WAN status. A WAN address in 100.64.0.0/10, 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16, paired with a different public IPv4 here, means the ISP is translating. Matching public addresses mean you are not behind CGNAT at the moment. Reboot once and see if the public address changes before you call it static.

## What ACT sells

Some ACT plans put customers behind CGNAT and sell a public or static IPv4 separately. The only reliable price is the one ACT puts on your bill or your ticket. This site will not invent one, and a VPN is not a substitute: the far end is a datacenter address, which is a different kind of shared.

Wrong city, right network? Use the [location checker](https://ipinfo.fyi/tools/location). Do not buy a static IP to correct a database.

## Questions

### Does ACT Fibernet use CGNAT?

Some ACT plans do, and some include a public IPv4. AS18209 and AS24309 only tell you the address is on ACT’s network (CABLELITE-AS-AP). Check the router.

### What is CABLELITE-AS-AP?

It is the RDAP name this site has for AS18209 and AS24309. PeeringDB lists AS18209 as Atria Convergence Technologies, the company behind ACT Fibernet.

### How do I get a static IP on ACT?

Ask ACT whether your plan is behind CGNAT and whether a public or static IPv4 is sold separately. Confirm the charge on your bill or a ticket. Do not use a price from a forum.
