Popular questions about products, connection, and how the service works
Information is current as of June 2026. The list of products, locations, operators, and prices may change, please double-check the current pages in the dashboard before purchase.
1. Which products support p0f spoofing?
Network fingerprint spoofing (p0f) is supported on:
Datacenter proxies
ISP proxies
Mobile proxies (not in every location / operator)
For Mobile proxies there are exceptions by country and operator, the full list is in the p0f switching on Mobile proxies section.
On Residential and Unlimited Residential proxies, p0f spoofing is not supported.
More about the technology: Network fingerprint spoofing (p0f).
2. Which products support UDP?
UDP is supported on all products, except:
Residential and Unlimited Residential proxies in the US 🇺🇸 location (a restriction from American providers since early 2026)
Premium Residential proxies in all locations
On Datacenter, ISP, Mobile, and non-US Residential proxies, UDP works normally.
More info: About the UDP protocol.
3. Is QUIC supported?
Yes, QUIC is supported on every proxy where UDP works (see question 2). However, your software also needs to support QUIC.
For example, in the Vision browser you need to turn on the Enable QUIC option in settings.
4. Which proxies are static (with a fixed IP)?
Fully static proxies (the same IP for the entire rental period) are only:
Datacenter proxies
ISP proxies
Residential and Mobile proxies are rotational by nature, their IP changes during use (see questions 11 and 14 below).
5. Which products are individual (one order = one user)?
Sold without sharing, on a one-per-user basis:
Datacenter proxies - one IP per user
ISP proxies - one IP per user
Mobile proxies - one port (one SIM card) per user
Residential proxies work through a shared address pool and are not individual.
6. I just bought / renewed a Datacenter or ISP proxy - it doesn't work
After purchasing or renewing a Datacenter or ISP order, 1-2 minutes are needed to sync the order with the proxy server. If after a few minutes the proxy still doesn't respond, please contact our Support.
7. How long do I have to renew a Datacenter / ISP proxy?
Renewal for Datacenter and ISP proxies is available only within 3 days after the rental period ends.
If the order isn't renewed within 3 days, it is deleted permanently. You won't be able to recover the same IP address or order after that.
We recommend enabling the Auto renew option in the order settings so renewal is charged from your balance automatically.
8. I just bought a Mobile proxy - it doesn't work
After purchasing a Mobile proxy, the port needs to be activated in one of these ways:
The Restart proxy button in the order settings
Following the personal Reset URL link from the order
If you don't use the proxy, after 3 hours the port goes into power-saving mode. This limit can't be removed, to bring the proxy back simply hit Restart proxy or the Reset URL again.
9. Are Mobile proxies unlimited in traffic?
Yes, Mobile proxies are unlimited in traffic. There's no cap on the volume of downloaded gigabytes, you only pay for the port rental period.
10. Why does my IP change periodically on Mobile proxies?
Mobile proxies sit on our mobile farms and operate via real SIM cards. IP address changes depend entirely on the carrier:
On average the carrier refreshes the address once a day.
The carrier may initiate a pool change at any moment, and the address will change earlier.
This is a feature of how mobile internet works and is outside our control. If you need rotation on a timer or by hotkey, use the IP Rotation feature in our extension.
11. What are TTL and Sticky on Residential proxies?
TTL (Time-To-Live) is the session "lifetime" in seconds. Once TTL expires, the proxy chain is rebuilt and you get a new IP. Range: from 60 to 86400 seconds.
Sticky / Random is the session mode. Sticky tries to hold the same IP within TTL, Random issues a random IP on every new connection.

12. What is the Relay parameter on Residential proxies?
Relay is the balancing (fallback) server through which your traffic enters the pool of Residential devices. The Relay is chosen based on where you're connecting from, to make the route shorter and more stable.
By default, EU is used
Also available: RU and UA
The Relay choice does not affect the endpoint IP country, it's purely a balancing server. The endpoint country is set by the Country parameter in the order settings.
13. What happens if I run out of traffic on Residential proxies? Does it expire?
No, traffic does not expire - it stays available until you spend it. If the traffic runs out, the proxies temporarily stop working, but it's enough to click Add traffic in the top-right corner of the order, top up the package, and the proxies will start working again immediately.
14. Why does my IP change periodically on Residential proxies?
Residential proxies are hosted on the home devices of real users who take part in a paid traffic-sharing program. These devices may:
leave the sharing network (for example, the owner turned the device off),
experience signal / connectivity issues.
Any of these reasons leads to an IP change during the session. We don't manage the devices in the pool directly.
If a session is misbehaving or dropping often, there are two ways to change the address:
Method 1. Click Generate proxy in the order, you'll get a new connection string.
Method 2. Change the SID manually in the connection string. For example, in this string:
the login contains a fragment sid-8dbryym0a32i. If you change one character in it, for example to sid-8dbryym0a324, the IP address will change. The same thing happens "under the hood" when you click Generate proxy.
SID is responsible for picking the device and the IP for your session.
15. Why do I get Google / Cloudflare captchas often?
Google and Cloudflare captchas are usually not related to the proxy itself, but to the browser fingerprint. The most common causes:
An outdated or low-quality antidetect browser is used
The profile has a "sticky" / repeating fingerprint
The browser leaks mismatched parameters (timezone, language, WebRTC, etc.)
What to do: generate new profile fingerprints whenever there's an issue, use quality antidetect solutions (for example the Vision browser), and verify leaks at IP Checker.
16. What restrictions do you have on the proxies?
On all products the following are blocked:
Service ports often used for brute-force attacks: 22 (SSH), 23 (Telnet), 25 (SMTP) and several others.
Banking and government websites, and Stripe and PayPal payment processors (this is a regulatory requirement).
The full list of restrictions by port, by site, by product-specific exceptions, and the limits for Unlimited Residential proxies are in the Limitations section.
17. Which payment systems are supported?
We accept payments via:
Stripe - bank cards, minimum payment $5.
Cryptomus - cryptocurrencies (BTC, LTC, USDT, and others).
About crypto payments through Cryptomus:
Payment via BTC or LTC may take up to 1 hour to process, this depends on network confirmations, not on our system.
Payment via USDT requires a minimum payment of $15 and a fee on the client side. This is a Cryptomus platform requirement, we have no influence over these terms.
18. Do you have an API?
Yes, we have a full user API.
Specification and Try-it-out: the User API section in this GitBook.

24. I need an IPv4 connection, why is there a domain in my connection string?
On Mobile and Residential proxies the default connection address is a domain name, behind which there are many IP addresses. Balancing (backconnect) servers sit behind the domain, and the connection to the proxy devices is made through them, so we don't hand out a direct IPv4 in the string by default.
Example connection strings:
If your software strictly requires IPv4, you can resolve the domain and substitute the resulting address for the domain name.
Option 1. Via a website. Open www.nslookup.io, enter the domain from your connection string, and you'll get a list of IPv4 addresses. For example, if the query returned 172.67.72.239, then instead of mobile.eu.proxyshard.com you can put this IP:
Option 2. Manually from the terminal. On Windows or Linux run:
The Addresses section of the response will contain the IPv4 addresses — take any of them and use it instead of the domain.
There are several servers behind the domain, and their IPs may change. If a connection with a hard-coded IP stops working, resolve the domain again and substitute the new address.
25. Do you have IPv6?
No, we sell IPv4 proxies only.
26. How does rotation (IP change) work on mobile proxies?
In addition to the automatic address change on the operator's side (see question 10), you can change the IP manually, no more than once per minute, in one of two ways:
follow the personal Reset URL link from the order;
press the Restart proxy button in the order settings.
More about the order fields is on the Mobile proxies page.
27. Is there channel-consumption monitoring on the proxies?
Measuring the speed of the consumed channel is not built into any of the products. The following accounting is available:
Unlimited Residential — there is an active-connections counter;
Residential — there is spent-traffic statistics (in gigabytes);
on the other products (Datacenter, ISP, Mobile) traffic measurement and request logging are not performed.
28. Why is Cloudflare DNS used on Standard and Unlimited residential proxies?
This is because, at the moment, DNS queries to the operators' servers are disabled on these plans, and resolving goes through public DNS (Cloudflare).
On ISP and Premium Residential proxies there is no such limitation.
29. How do I achieve the lowest latency (ping) on a proxy?
On residential and mobile proxies, the latency to the end node depends on several factors:
the current load on the operator's base station;
the signal quality on the device sharing the traffic;
how far you are from the connection point.
In addition, the main balancing servers are located in the Netherlands. When connecting to locations like the USA or Africa, on top of your latency to the balancer there is also the overhead latency between the Netherlands server and the final proxy. Shortening this route is not possible.
If minimal latency and speed are critical, use Datacenter or ISP proxies. They have extremely low connection overhead: there is no layer of balancing servers, the connection is direct.
For the lowest possible ping, connect from the same country where the proxy is located. This is usually achieved by renting a VPS / VDS / Bare-Metal server in the required country. For example, for ISP proxies in the USA it's ideal to work through a VPS in New York — the ping will be minimal, whereas connecting from Europe it will be at least 80–120 ms.
30. What timezone does the site use?
