Detailed explanation of proxy knowledge: What are dynamic proxies and static proxies, and what are the differences
by louise

With the rapid development of the Internet, proxy services play an increasingly important role in daily life and work. The proxy service can protect the user's real IP address, improve network access speed, protect user privacy, etc.


Among proxy services, dynamic IP proxies and static IP proxies are the two most common types. This article will explain dynamic IP proxies and static IP proxies in detail and compare the differences between them.


1. Dynamic IP proxy


Dynamic IP proxy is a proxy service that dynamically assigns IP addresses at runtime. When a user accesses the Internet through a dynamic IP proxy, the proxy server assigns it a temporary, available IP address.


Compared with static IP proxy, dynamic IP proxy has the following characteristics:


Dynamic changes in IP addresses: Since the IP addresses used by dynamic IP proxies are temporary, each time a user requests access, the proxy server will assign them a new IP address. This means that the same user may access from different IP addresses within a short period of time.


More flexible: Due to the dynamic changes of IP addresses, dynamic IP proxy can circumvent the blocking or restrictions of the same IP address by the target website to a certain extent. At the same time, it is also suitable for application scenarios that require frequent changes of IP addresses, such as data capture, web crawlers, etc.


Higher security: Since the IP address used for each visit is temporary, dynamic IP proxy can better protect user privacy and security. Even if a data leak occurs or is tracked, it is difficult for trackers to locate specific users due to the constant changes in IP addresses.


Lower cost of use: Dynamic IP proxies are usually paid on-demand, and users only pay for the IP addresses they actually use. This gives users more flexibility to control costs.


However, dynamic IP proxies also have some limitations and challenges:


Availability limitations: Since IP addresses are temporary, users need to ensure that they have an available IP address for each use. During periods of high demand, such as specific time periods or events, you may experience a shortage of IP addresses.


Bandwidth limitations: Dynamic IP proxies may offer smaller bandwidth or data transfer limitations compared to static IP proxies. This may affect user experience in scenarios with large amounts of data transfer or high bandwidth requirements.


Reliance on third-party services: Dynamic IP proxy relies on the services of proxy servers and network operators. If there is a problem with the server or network, users may be affected. In addition, since IP addresses are leased or purchased, there are also certain legal and compliance risks.


2. Static IP proxy


Static IP proxy is a type of proxy service that uses a fixed IP address. When users access the Internet through a static IP proxy, they always use the same IP address.


Compared with dynamic IP proxy, static IP proxy has the following characteristics:


Fixed IP address: The IP address used by a static IP proxy is fixed and will not change. This means that users always use the same IP address for consecutive visits.


High availability and stability: Since the IP address is fixed, static IP proxies have advantages in connection stability. Users can expect more reliable and stable connection performance.


Suitable for specific application scenarios: Static IP proxy is suitable for application scenarios that require long-term connection maintenance or high stability requirements, such as online games, remote office, etc. In these scenarios, a fixed IP address helps reduce the risk of being blocked by the target server.


Higher cost: Since the IP address of a static IP proxy is fixed, maintenance and management costs may be higher. Users may need to pay more to rent or purchase a fixed IP address.


There are certain security risks: Because static IP proxies use a fixed IP address for access, users may be at risk if the address is attacked or security issues arise. In addition, for users who need to do a lot of data scraping or crawling work, fixed IP addresses are easier to identify by target websites.


To sum up, dynamic IP proxy and static IP proxy each have their own characteristics and applicable scenarios. Users need to choose which type of proxy service to use based on actual needs.


When choosing a proxy service, you also need to consider factors such as security, stability, availability, and cost. LunaProxy provides pure static residential proxies and dynamic residential proxies. No matter which proxy you need, you can choose LunaProxy.
