These articles are for people deciding which proxy type to buy, for people setting one up in a browser, and for teams checking that their ad campaigns ran as booked. ProxyJam sells one product, static residential (ISP) proxies, publishes a free browser extension, and publishes these articles. The blog carries no industry news, no roundups and no rankings of the vendors we compete with.

How are the articles chosen and kept up to date?
Each article answers a question people search for before they pick a proxy type or while they set one up, and a new one is added when a question comes up that none of these answers. Every article shows the date it last changed, cites the public standards and registries its argument rests on, and says, under its table, how the verdicts were reached. Sourcing and corrections are covered by our editorial policy, which also explains how to report a mistake.
If you already know what you need, the ISP proxies page has the catalogue: static addresses in 77 countries, each on a named carrier. Otherwise, start with the definition article, whose links lead to the three comparisons in reading order.
