The arithmetic behind a shared address
Why a Colombian public address is often shared
IPv4 is the older address system, and most of what Hulu reads still arrives over it. Colombia has far fewer IPv4 addresses than it has connections.
| Measure | Colombia | Source and date |
|---|
| IPv4 addresses registered to Colombia | 17,513,984 | LACNIC data, 28 September 2026 |
| People | About 53 million | DANE projection for 2025 |
| IPv4 addresses per 100 people | About 33 | Our division of the two rows above |
| Mobile internet accesses | 49.75 million | CRC, end of 2025 |
| Fixed internet accesses | More than 10.3 million, 55.2% of them fibre | CRC, end of 2025 |
| Users who can reach sites over IPv6 | 19%, against 45% across the Americas | Internet Society Pulse, 2026 |
Read the mobile row against the first one: Colombia has almost three mobile internet accesses for every IPv4 address registered to the country, before a single home, office or server is counted. The registry files addresses under the country where each holder registered, so the match is not exact — but a gap that wide is hard to close without many connections sharing one address.
Where addresses run short, the usual answer is carrier-grade NAT, or CGNAT: the operator puts many customers behind one public address. We have not seen a Colombian operator document its own arrangement, so we name no operator. What matters for Hulu is simpler. A shared address carries the history of everyone behind it, and Hulu’s help centre lists an address “block listed because of previous anonymous proxy use” among the causes of its location error.
IPv6, the newer system, has enough addresses for every device. Only about one Colombian user in five can use it, so it matters less here than in countries where most traffic runs over it — but a single look at an address checker settles it for your line.
This is also why the same account can behave differently on home fibre and on mobile data: the two reach Hulu from different addresses, each with its own history. The home address matters for televisions too: USip’s Smart DNS recognises your home by it, so if your operator changes that address, register the new one.
