Next, I will tell you about the dynamic types of IP in official website, which are short-lived and suitable for batch account registration or data capture and so on.Dynamic residential proxyThe dynamic residential proxy is also called the flow residential proxy. This plan charges according to the consumption flow. The flow is calculated from the day of purchase, and the flow will expire after the corresponding effective time. Therefore, customers are advised to buy a flow package they need one day before the flow expires to extend the use time. This package allows you to choose a country's IP and target some states and cities. It can be used on PC and mobile phone, and supports API mode and User+Pass Auth mode. However, if you use it on a mobile phone, you must select the User+Pass Auth mode.Our proxy has no limit on the number of requests and concurrent sessions, and switches flexibly, and the success rate of connectivity is as high as 99.9%.The frequency of API connection extraction is once per second, and up to 1000 IP can be extracted at one time. If you have other additional requirements, you can contact customer service for help. Real and pure proxy IP only supports HTTP(S) or SOCKS5 protocol, providing an efficient and smooth network crawling experience and easily obtaining the available data in the target website. Each time a request is sent, a new IP address is assigned to the user's computer, and the real IP address is hidden behind the proxy server, which will not be restricted or banned by the filtering mechanism, thus realizing unlimited requests and high anonymity.If you choose API mode, you must add the current IP displayed on your official website to the white list, which is the authentication mechanism of IP2World. Before using the network proxy service, you need to add your current IP address to the white list, or you can let the currently used device generate an API link to automatically add your current IP address to the white list. Under the API mode acquisition proxy, the server will be maintained and upgraded irregularly, and the IP: port will also change. The default IP rotation time is about 5 minutes. If you choose User+Pass Auth mode, user name password authentication allocates traffic by creating an authentication account for the main account. The main account can set the user name, password and traffic limit of the authentication account, and generate the proxy together with the country and region parameters. If you use the account secret authentication proxy mode, each IP can be used for 5-120 minutes, and you can choose the sticky IP and set it yourself.Dynamic unlimited proxyDynamic unlimited proxy is a new package based on dynamic flow residential proxy. They have similar functions, but the difference is that unlimited proxy is unlimited flow and IP. It can't choose a region but supports random distribution in more than 50 countries. If your business needs a lot of traffic, this package is very suitable. Only HTTP(S) or SOCKS5 protocols are supported.Our unlimited proxy does not support the selection of countries and cities, but it can support the selection of continents. Our unlimited plan is to have an IP pool of 50 million (50 million) and live online of about 1.5 million (1.5 million). You can test whether it is suitable for your business online, and we will try our best to meet your needs.Its usage can refer to the usage of dynamic residential IP, but the difference is that the unlimited package also needs to add IP whitelist when using User+Pass Auth mode. In fact, whether you use API mode or User+Pass Auth mode, you must add IP whitelist before obtaining IP links.S5 proxySOCKS5 proxy server is a type of proxy running through TCP Internet protocol. It supports optional proxy IP location, API mode, SOCKS5 and HTTP(S) protocols, and needs to be bound with IP at the client. Dynamic S5 residential proxy, if the IP is online, the maximum single binding time of each IP can last for 6 hours (IP can last for several minutes to 6 hours). If the IP is still online, you can bind the same IP again or add it to your favorites to use it for a longer time. Please note that our S5 proxy is a dynamic residential IP, and the duration is random. Please understand.This package is charged according to the IP amount, and you need to download the client to use it. You can generate one or more proxy IPS for one or more browsers. The proxy in this package is a dynamic residence. It can only be used on computers that are successfully bound. At present, there is no way to use it on the mobile phone, because the IP of the mobile phone cannot be added to the white list of the client.Unlimited devices can log in to the same account and use the proxy at the same time. The IP2 proxy manager of a PC can be connected by multiple devices, and the IP of s5 package does not need to create an authorized user and password, just configure the local proxy and port to the browser or software you want to configure after binding the IP or obtaining the IP link.
