For a private IPv4, compare both services for the country and term you need. If you need ISP, residential or mobile proxies, start with the matching Proxy-Seller product. For a shared IPv4 and for MTProto for Telegram, look at Proxy6.
First check that the product fits your application. A discount on an IP that does not fit does not solve your problem.
One US IPv4 for a month: what the order forms showed
On 4 October 2026 we picked the same setup in the Proxy-Seller calculator and the Proxy6 form: a private IPv4, USA, one IP, a "1 month" term.
- Proxy-Seller: $1.80 before the code. In the open order form, the code
researchedgave aSuccessmessage, a $0.27 discount and a total of $1.53. The extra option of automatic IP replacement was not on. - Proxy6: the calculator showed 120 ₽ before the code. The next step opened registration, so we never got as far as applying the coupon.
This is an observation before payment: no account login, no email, no payment method chosen and no purchase. Prices are left in their original currencies. To choose on cost, compare the amounts in your payment currency, including the exchange rate and fees. The Proxy6 result after the coupon is not confirmed here.
The Proxy-Seller form also had the auto-renewal switch turned on. The note pointed to renewal every 30 days and the need to link a card after payment. Check this switch before a one-off order. This observation does not establish how the code applies to other countries, terms, products or renewals.
Current offers and links to the providers: Proxy-Seller promo code and Proxy6 promo code. For other services, see the promo code catalog. We do not know when these codes end in our catalog.
Which product you actually need
One permanent address for a work application. Start with a private IPv4 from Proxy-Seller or Proxy6. Check that the country is available, which protocol is supported and how you authenticate. Both describe HTTP(S)/SOCKS5 and authentication by login and password or by IP: Proxy-Seller FAQ and Proxy6 FAQ. That still does not confirm that a given address works with your service.
Cheap IPv6 instead of IPv4. First check that the target site supports IPv6. Proxy6 states this limit outright. Its minimum rental is 3 days for IPv6 and 7 days for IPv4/Shared. So a short IPv6 check and a week of IPv4 are different orders, even if both are sold as one address.
Static ISP, home networks or a mobile carrier. Proxy-Seller has separate ISP, residential and mobile products. Ask about the session mode you need: a static ISP and holding an address in a rotating residential pool are different services. To choose by task, open static, residential or mobile proxies.
A shared address, or Telegram only. In the Proxy6 form, IPv4 Shared is listed as an address for at most three customers, and MTProto as a product for Telegram only. Choose Shared if you do not need exclusive access to the IP. MTProto does not replace HTTP(S)/SOCKS5 for an arbitrary application.
Working with Avito. Proxy6 says plainly in its FAQ that its proxies do not work for this (Avito is a Russian classifieds site). There is no point in a random purchase just to test it.
What happens if the address does not fit
At Proxy6, a refund is possible in the first day if the proxy does not work, after the provider checks it. There is no refund for IPv4 Shared. This is not a free test of any use case.
At Proxy-Seller, the policy lets you ask for a refund within 72 hours on the listed grounds, with fees excluded. For a weekly product the window is usually 24 hours, and the three-day residential trial plan is non-refundable. State your real task in the order: a change in what you want to use it for does not by itself give you the right to a replacement.
The decision before you pay
- Pick the product for your application, then the country and the shortest term that fits.
- Compare the full totals of identical orders, IP availability and refund terms.
- Apply the code to the order you chose, then check the total and auto-renewal.
We did not compare IP quality or speed for these services. After you buy, test a small volume in your own permitted workflow using the proxy testing checklist. If the code does not change the total, use the guide to checking a discount.
