I have now written up a great many proxy pricing pages, and IP2World has the lowest number I have seen: nineteen cents a gigabyte.

That is not a headline rate with a catch buried underneath. It is the IPv6 datacenter tier, and understanding why it is so cheap tells you exactly when to use it.

The Full Price Ladder

What is unusually good here is that every tier is published side by side, so the trade is visible.

IPv6 datacenter sits at the bottom, under twenty cents. IPv4 datacenter and rotating residential sit around seventy cents. Rotating ISP is around a pound a gigabyte. Mobile 4G and 5G costs a few times that, as carrier traffic always does.

Coverage runs across fifty plus countries with HTTP, HTTPS and SOCKS5, unlimited sessions and instant delivery.

Why IPv6 Is So Much Cheaper

Worth explaining, because it is the whole reason for that number.

IPv4 addresses ran out years ago. They are a finite, traded, genuinely scarce asset, and their price reflects that.

IPv6 addresses exist in quantities that are difficult to describe meaningfully. There is no scarcity, so there is no scarcity premium.

The catch is compatibility. Your target has to support IPv6, and a large share of the web still does not. So IPv6 is not a cheaper version of what you were buying. It is a different tool that happens to be nearly free where it applies.

The sensible approach is to test your target for IPv6 support first. If it works, you have just cut your bandwidth costs by roughly three quarters.

Unlimited Sessions

Session limits are one of the quieter caps in this industry. A plan gives you generous bandwidth and then restricts how many concurrent sessions you can hold, which throttles everything downstream.

Removing that limit means your concurrency is governed by your own infrastructure rather than by a line in the terms.

Mobile Sits at the Top for Good Reason

The mobile tier is the most expensive per gigabyte by some distance, and that is honest pricing rather than a markup.

Carrier addresses genuinely cost more to supply, and they are worth it on targets that reject everything else. Having the whole ladder from IPv6 at the bottom to mobile at the top under one account means you can match spend to difficulty per job rather than per vendor.

Who It Fits

IP2World suits high volume work where bandwidth cost dominates, anyone whose targets support IPv6, users who want to escalate from cheap to premium without changing provider, and cost sensitive projects that still need mobile occasionally.

Who Might Look Elsewhere

Fifty plus countries is decent but well short of the 195 figures elsewhere. If you need genuinely global long tail coverage, look at a broader provider.

If your targets do not support IPv6, the headline rate is irrelevant to you and the mid tiers are competitive rather than exceptional.

Final Verdict

IP2World is the right provider when bandwidth cost is your binding constraint.

A complete ladder from IPv6 datacenter through residential, ISP and mobile, all published openly, with unlimited sessions and instant delivery.

Test whether your target speaks IPv6 before anything else. If it does, this is one of the cheapest ways to move serious volume. If it does not, work up the ladder and check each tier with our proxy checker before committing.
