Flow Jamaica's network at a glance

Flow Jamaica operates two active AS numbers (Autonomous Systems) that you might see when you look up your IP:

AS30689

FLOW-NET (Columbus Communications Jamaica)

Primary residential and business ASN. This is what most Flow customers see today.

AS10292

CWJAMAICA (legacy Cable & Wireless Jamaica)

Older ASN still active from before the Columbus/C&W rebranding. Still announces around 70 IP prefixes.

Both ASNs route through Flow’s infrastructure in Kingston before transiting to Miami (NAP of the Americas, 50 NE 9th Street, Miami). Nearly all Flow Jamaica internet traffic — and most Caribbean internet traffic in general — exits through Miami.

Dynamic vs static IPs — which does Flow give?

Residential customers: dynamic IP. Unless you have a business contract, Flow gives you a dynamically assigned IP address from their pool. This means your IP can change:

  • When your modem reboots or loses power
  • When Flow rotates their DHCP leases (usually every few days to weeks)
  • If your service is disconnected and reconnected

Business customers: static IP available. Flow Business offers static IP addressing as an add-on to business internet plans. You’ll need to request it explicitly — it’s not automatic. There’s typically a monthly fee on top of your base plan. If your business needs a consistent inbound address (for VoIP, remote access, or servers), this is the right path.

CGNAT — why your IP might look shared

Many Flow residential customers are behind CGNAT (Carrier Grade NAT), also called “shared IP” addressing. Here’s what that means in practice:

Instead of assigning a unique public IP to every modem, Flow uses a large NAT device that lets many customers share a single public IP. From the outside internet, you and your neighbors might appear to come from the same IP address.

Why this matters:

  • Running a server from home (Minecraft, web server, VPN endpoint) typically doesn’t work behind CGNAT without port forwarding agreements with Flow
  • Some online services that rate-limit by IP may affect you and your neighbors simultaneously
  • Your “IP address” as seen by websites may be shared with many other Flow customers

If you need a routable public IP for a home server or business use case, you’ll need either a Flow Business plan with static IP, or a VPN service that routes your traffic through a dedicated exit node.

How to check your current Flow IP

The fastest way is this site. Go to checkmiip.com and your IP appears immediately, along with the ISP label (which will show “Flow Jamaica” for most Flow connections) and your approximate parish.

Other things you can check from the home page:

  • Is your connection on IPv6? If an IPv6 address appears below your IPv4, Flow has provisioned IPv6 on your line — increasingly common on newer residential connections.
  • Which Cloudflare data center is routing you? The “Nearest server” field on the detail card shows the CF colo that handled your request. Flow residential users in Kingston typically hit KIN (Kingston, JM) or MIA (Miami, FL).
  • DNS leak check. If you’re on a VPN, use our DNS leak test to confirm your Flow IP isn’t leaking through.

Flow Jamaica IP ranges

Flow Jamaica’s address space is registered through ARIN (American Registry for Internet Numbers) under Liberty Latin America and Columbus Communications. Common ranges you’ll see assigned to Flow residential and business customers include:

IP rangeASN
72.252.x.xAS30689
207.204.x.xAS10292 / AS30689
200.10.x.xAS10292 (legacy C&W)
208.131.x.xAS10292 (legacy C&W)

Ranges are approximate — Flow’s full CIDR blocks span many /24 prefixes. Source: ARIN WHOIS / HE BGP Toolkit, May 2026.
