The arithmetic behind the addresses
IPv4 scarcity and IPv6 in Argentina, in plain numbers
Two address systems run side by side: IPv4, the original one, which has run out, and IPv6, its far larger successor. Both matter for a Hulu test, for different reasons.
| Measure | Argentina | What it means |
|---|
| IPv4 addresses registered to the country | About 19.4 million | The third-largest total in Latin America and the Caribbean, 10.7% of the region’s |
| People, 2025 | About 45.9 million | Roughly 0.42 IPv4 addresses per person — one for every 2.4 people |
| New IPv4 from the registry | Pool exhausted since 19 August 2020 | LACNIC puts the wait for returned addresses at more than ten years |
| Users who can reach sites over IPv6 | 31% | Below the 45% average for the Americas — about one Argentine user in three |
With fewer addresses than people, sharing is built into the system. LACNIC, the registry for the region, advises operators to run IPv6 alongside IPv4 and to treat CGNAT — carrier-grade NAT, one public address shared by many customers — as a temporary answer to the shortage. The lesson for Hulu is about the U.S. side: its help page lists an address “block listed because of previous anonymous proxy use” among the causes of its location error, and a shared address carries the history of everyone who used it — so the U.S. address you use should belong to one household, not a crowd.
The IPv6 figure cuts the other way. Where a line has IPv6, your laptop or phone holds an Argentine IPv6 address next to the IPv4 one, and a U.S. connection that carries only IPv4 leaves that second route open. With about a third of users in that position, it is common enough to check every single time.
One note for televisions set up with USip’s Smart DNS: it recognises your home by its public IP address, so if your provider changes that address, the new one has to be registered with USip.
The one-line rule: when you check your address, check both kinds. An IPv6 address from an Argentine provider on the checker means Argentina is still in play, whatever the IPv4 line says.
