Guides, tutorials, and analysis from the ColdProxy team on proxy services, web scraping, IP rotation, online privacy, and public-data collection. Learn how residential IPv4, residential IPv6, and datacenter IPv6 proxies work — and pick the right one for scraping, ad verification, social media, and e-commerce.
Before you write a line of code, you need to know whether you are building a crawler, a scraper or both. Pick wrong and you either hit a site far harder than the job needs, or you end up with a pile of URLs and no data.

A product page in Berlin can look nothing like the same page in Boston. The price, currency, language, cookie banner and ads can all change, and your office IP will never show you any of it.

Quick answers to the questions new proxy users ask most often.
A proxy server is an intermediary between your device and the internet. It routes your traffic through a different IP address, masking your real location and identity. Businesses use proxies for web scraping, ad verification, market research, and managing multiple accounts without triggering platform security checks.
Residential proxies use real IP addresses assigned by internet service providers to home users — they look like ordinary visitors and are hard to detect. Datacenter proxies are hosted in cloud infrastructure, so they are faster and cheaper but easier for sites to flag. Most teams start with datacenter IPs for speed-sensitive work and upgrade to residential for scraping protected targets.
For protected targets such as search engines, e-commerce, and social platforms, residential proxies are usually the safest starting point. For simpler targets and high-throughput jobs, datacenter IPv6 proxies are faster and cheaper. Rotate IPs where needed, respect rate limits, and pair the right proxy tier with your target's defenses.
Yes — proxies are legal in most jurisdictions when used for legitimate purposes like market research, brand protection, ad verification, and accessing publicly available information. You are responsible for following the terms of service of the sites you access and the laws of your country. ColdProxy does not permit use for fraud, illegal content, or abuse.
Static proxies keep the same IP for the life of the session — ideal for managing accounts, checkout flows, or anything that needs a consistent identity. Rotating proxies swap IP every request or on a schedule — ideal for large-scale scraping where each request should look like a new visitor.
Free trials may be available after individual review. Tell us what you want to test and the capacity you need on Telegram or in a support ticket. We assess each request and confirm availability and trial terms before providing access. To start right away, use the shortest public billing period available for the product you want. Residential IPv4 (Unmetered) and Residential IPv6 currently offer hourly buying, while Datacenter IPv6 starts at daily billing and Residential IPv4 (GB Based) uses monthly traffic packs.
