United States datacenter proxies: dedicated IPv4 by city

How many IPv4 addresses does United States have?

ARIN, the regional internet registry for United States, had delegated 1,606,309,024 IPv4 addresses to organisations in United States by 19 October 2026. That is 43.56% of all IPv4 space delegated worldwide and ranks United States 1st of 240 countries and territories. Among the 22 countries on RackProxies it comes 1st, before Japan (188,705,088).

Every free pool of IPv4 has run out, so a United States datacenter IP is a scarce, leased resource: that is why datacenter proxies are billed per IP and per month rather than per GB. United States also holds 147,639 IPv6 blocks of /32 size and 32,267 ASNs (network numbers). RackProxies sells IPv4 only; IPv6 is not sold yet.

Where are the datacenters in United States?

The US has more ARIN delegations than any other country, and its datacenter markets spread from Northern Virginia to Silicon Valley.

The operators with the most facilities there in PeeringDB are Digital Realty (65), DataBank (62), Equinix (48) and Lumen (45).

Which IP will a United States datacenter proxy give me?

A United States rental gives you IPv4 addresses held by hosting or transit networks in the United States; nobody else uses them during your 30 days. A lookup of its network shows a hosting ASN registered with ARIN, not a United States home broadband provider. Most databases place it in the United States, often in Ashburn; to confirm, run the datacenter IP check.

Which law applies when you collect data from United States sites?

The United States has no general federal privacy law; state laws such as the California Consumer Privacy Act (as amended by the CPRA) apply to personal data of their residents. A United States datacenter IP changes where requests come from, not who is responsible for any personal data collected from United States sites. RackProxies is for public, non-personal data, tests of your own services and allowlisted access; the acceptable use policy lists what is blocked. Not legal advice.

How much do United States datacenter proxies cost?

As of October 2026, a United States datacenter IP costs $1.29 for 30 days, the same price as every other country on RackProxies; 100 IPs cost $59.25 ($0.59/IP). Prices are per IP and per 30-day rental, not per GB.
