Part I: Understanding the Basic Concepts of Proxy IPs

In the online world, we often hear the concept of "proxy IP". So what is a proxy IP? Simply put, a proxy IP is an intermediary that sends requests or receives responses on your behalf. By using a proxy IP, we can hide the real IP address and increase the privacy and security of accessing websites.

Part II: Characteristics of Dynamic Proxy IP

Dynamic proxy IPs have many differences compared to static proxy IPs. First of all, Dynamic Proxy IP is changeable at any time, while Static Proxy IP is fixed. This means that we can change the dynamic proxy IP at any time to cope with some network activities that require frequent IP changes, such as crawling website information, swiping votes and so on. Secondly, dynamic proxy IP can simulate the behavior of real users, which makes our operation more realistic and reduces the risk of being blocked by websites. In addition, Dynamic Proxy IP can also realize load balancing, spreading requests to different proxy servers to improve access efficiency.

Code Example:

import requests

def get(url):
proxy = {
"http" : "http://dynamic_proxy_ip:port",
"https" : "http://dynamic_proxy_ip:port"
}

try.
response = requests.get(url, proxies=proxy)
print(response.text)
except requests.exceptions.ProxyError: print("Proxy error occurred!")
ProxyError: print("Proxy error occurred!")

Part III: Characteristics of static proxy IPs

Compared to dynamic proxy IPs, static proxy IPs have some unique characteristics. First, static proxy IPs are fixed and do not change over time. This feature is suitable for network activities that require high IP stability, such as when servers provide services to the outside world, static proxy IPs can be used to ensure the stability of services. Second, static proxy IPs generally come from specialized proxy service providers and can be acquired through purchase or lease. Static proxy IPs are of higher quality due to high stability and reliable providers.

Code Example:

import requests

def get(url):
proxy = {
"http" : "http://static_proxy_ip:port",
"https" : "http://static_proxy_ip:port"
}

try.
response = requests.get(url, proxies=proxy)
print(response.text)
except requests.exceptions.ProxyError: print("Proxy error occurred!")
ProxyError: print("Proxy error occurred!")

Part IV: Choosing a Dynamic Proxy IP or a Static Proxy IP?

When choosing whether to use a Dynamic Proxy IP or a Static Proxy IP, we need to decide based on our specific needs. If our network activities require frequent IP changes and we want to simulate the behavior of real users, then Dynamic Proxy IP is a better choice. If our needs are more stable and require higher IP quality, then a static proxy IP may be more suitable for our needs.

Part V: Summary

To summarize, Dynamic Proxy IP and Static Proxy IP have their own unique characteristics. Dynamic proxy IP can be changed at any time to simulate the behavior of real users, which is suitable for network activities with frequent IP changes and the need to protect privacy and security; static proxy IP is stable and reliable, which is suitable for network activities with high requirements on IP quality and the need to maintain stability for a long time. For specific needs, we can choose to use different types of proxy IP to achieve the best results.

Knowledge Points Supplement: The so-called proxy IP dynamic and static difference mainly refers to the variability and stability of the proxy server IP. In practical applications, we can choose the type of proxy IP that suits our needs in order to improve the efficiency and security of network activities.
