Web crawling and web scraping are often treated as the same activity, yet they solve different problems. Crawling is about discovery. Scraping is about collection. Teams that confuse the two usually build fragile pipelines that either miss pages or gather the wrong fields.

This guide explains the difference between web crawling and web scraping in practical terms. It covers definitions, workflows, tooling, scale, and the legal questions that accompany any serious data collection effort.

Web crawling vs web scraping at a glance

Baidu is the leading search engine in China, and its organic listings hold information that is difficult to obtain elsewhere. This guide explains how to scrape Baidu search results using Python and proxies in a structured, repeatable manner, covering setup, parsing, pagination, storage, and scaling.

The objective is a practical pipeline. You will learn to send a search query, parse the returned HTML, extract titles and links, and store clean structured data. There are several ways to scrape Baidu organic results, and the approach below uses standard Python tools so the code remains readable.

Why scrape Baidu organic results

What Is a UDP proxy?

A UDP proxy is a type of proxy that forwards User Datagram Protocol traffic between a client and a server. It acts as an intermediary for UDP, accepting each UDP packet from the client and forwarding it toward the destination IP address and port.

The destination server sees the proxy server IP address rather than the original client. As a low-level proxy, UDP proxies do not interpret application data. They simply relay datagrams, which is what makes UDP proxies suitable for fast, real-time transmission. UDP proxies stay protocol agnostic, forwarding almost any packet without inspection.

UDP proxies differ sharply from http proxies. HTTP proxies were designed for web traffic, while UDP proxies are designed to move UDP packets. In practice, almost every UDP proxy today is a SOCKS5 proxy that implements the UDP ASSOCIATE command.

Stable connectivity depends on two components working together: the proxy and the firewall. When either one holds the wrong configuration, applications fail to connect to the internet, requests time out, and pages quietly refuse to load for no obvious reason.

In this guide you will learn how to check proxy and firewall settings on every major platform. It explains how to check the proxy firewall and DNS configuration across operating systems and browsers, written as a clear and practical sequence for technical users.

What proxy and firewall settings are and why you should check them

Because it acts continuously and at high frequency, a stable proxy layer is a core part of the setup rather than an optional extra.

This guide explains why proxies are required, which types fit which tasks, how to configure them inside the program, and how to keep a healthy pool over time.

A proxy acts as an intermediary between a user and the wider network, but the direction it faces changes everything. The forward proxy vs reverse proxy question comes down to one thing: who the proxy represents.

This guide explains how each one works, where each fits, the trade-offs involved, and how to choose the right proxy for a given workload.

Both route traffic through an extra hop, yet they solve opposite problems. A clear grasp of the differences between forward and reverse proxies prevents costly architecture mistakes and keeps systems stable and measurable.

A proxy lets the claude code CLI send its requests through a controlled exit point instead of your raw connection. This matters for corporate compliance, stable automation, and consistent regional performance. This guide explains which proxy types fit, how to configure them step by step with screenshots, and how to verify the result. It also covers a quick browser setup for the claude.ai web app, so both the terminal agent and the browser can share the same controlled egress.

What a claude code proxy is – and when you need one

The phrase has two meanings, and confusing them causes most setup mistakes. The first is a network proxy: a server between the CLI and the internet that forwards requests and presents a single, controlled exit point. The second is a software gateway that re-routes model traffic to an alternative backend. Both are legitimate and solve different problems.

In today's digital ecosystem, every IP address carries a measurable level of trust. This trust, known as IP reputation, determines whether your messages reach inboxes, whether your servers are treated as legitimate, and whether mailbox providers consider your traffic safe. Understanding what ip reputation means for senders, how it is measured, and which sending practices influence it has become essential for any organization that relies on email communication or distributed server infrastructure.

This guide outlines the fundamentals of IP reputation, the factors that impact your ip reputation, and ten practical steps to improve your ip reputation across email and server environments.

We work with thousands of clients who run web scraping, market research, ad verification, SEO monitoring, and large-scale automation projects. The question we hear most often is simple: which proxy type fits my workload – ISP or residential? In this guide we explain how isp and residential proxies operate, where each one performs best, and how to choose the right proxy for your needs. The choice between isp and residential proxies usually comes down to scale, speed, and how strict the target endpoint is about ip diversity.

Quick Comparison: ISP vs Residential Proxies

Below is a quick reference table that summarises how isp proxies and residential proxies differ across the parameters that matter most for performance testing and analytics workflows.

We provide both IPv4 and IPv6 proxies, and we know that picking the right type of IP address can be confusing. The choice of IP version affects pricing, compatibility, and performance for everything from data collection to ad verification. In this guide, we walk through the key differences between the two protocol versions and help you decide which one fits your project.
