Where static residential IPs come from

“Static residential” is a product label, not a data source. There are only a few real ways to get those addresses, and the registry usually tells you which one you are buying.

Source 1: business lines resold

Small ISPs and local resellers sell business connections with fixed addresses. The ASN belongs to the ISP, the address stays stable, and it looks clean. These are the good ones — if the reseller actually controls the line.

Source 2: small ISP ranges

Some ISPs rent out blocks inside consumer ranges. The ASN looks residential, the reverse DNS often still says the ISP, and stability depends on the contract. Ask for the range and check who announces it.

Source 3: datacenter ranges with a residential sticker

The most common “static residential” pool is hosting space with a quiet relabel. The ASN is a hosting provider, the reverse DNS is missing or generic, and the price is suspiciously low.

How to tell in five minutes

• Look at the ASN owner: hosting company or ISP?
• Check reverse DNS: does it point at an ISP domain?
• Compare registry country vs geolocation country.
• Ask for the price per address; real static residential is not cheap.
