With the continuous expansion of cross-border e-commerce, overseas promotion, foreign trade services and other businesses, more and more users are starting to rent US servers. When choosing a server, there is an often overlooked but crucial question - should I choose a US dynamic IP server or a static IP server?
The stability and independence of the IP are directly related to the performance of a series of functions such as remote access, system deployment, domain name resolution, and SEO optimization.
Static IP refers to an IP address that is fixedly assigned to the server. Even if you restart the server, power off and reconnect, it will not change. This IP is unique within the global Internet. Unless you manually change it or the service provider recycles it, it will not change for a long time.
Dynamic IP is an address that is automatically assigned from the IP pool every time the server is started or the network is reconnected. It may come from different cities, network segments, or even operators. Many home broadband and basic VPS use dynamic IP by default.
Advantages and disadvantages of US static IP servers:
Advantages: Stable and predictable, always use one IP, no need to frequently update DNS or software configuration. It is beneficial to SEO and brand exposure. Search engines can more easily identify sites with fixed IPs and improve weight. Good for whitelist and remote authorization
Disadvantages: High cost, static IP is usually sold as a value-added item, the price is 10-50 yuan higher per month. Not suitable for circumventing blocking scenarios, high replacement cost after being blacklisted by the platform.
Advantages and disadvantages of US dynamic IP servers:
Advantages: Low cost, most VPSs are dynamic IP by default, and users do not need to pay extra. High flexibility, each IP refresh can bypass some regional restrictions and blockades. Variable IP can circumvent platform risk control and is suitable for high-frequency request scenarios.
Disadvantages: Easy to cause connection failure, domain name and port mapping scenarios that rely on fixed IP are prone to failure. Complex operation and maintenance, each IP change requires manual query and configuration update, and management is inconvenient. Not conducive to long-term service operation. If you deploy websites, databases, etc., IP changes will cause serious access anomalies.
How to determine whether the server is dynamic or static IP? The judgment method is very simple:
After restarting the server, check whether the IP has changed? You can query the public IP address through ipinfo.io. If the IP changes after restarting, it is a dynamic IP
Or consult the service provider's customer service and ask clearly: "Is this server an independent static IP? Does it support long-term binding?" Check the backend instructions. The cloud service backend will usually mark
Precautions for purchasing a US static IP server
Confirm whether it is a "real exclusive IP". Some service providers claim to be static, but they are actually "shared IPs allocated for a long time". Be careful to distinguish.
It is recommended to choose "CN2 line" or mainland optimized IP. If you access the US server from China, choose CN2 GIA/GT optimized line for smoother access.
Pay attention to the IP replacement policy. Some static IPs are "replaceable once" and cannot be used for a long time by default. Be sure to confirm clearly before purchasing.
Whether you are building a website, remote operation and maintenance, cross-border business or online marketing, the choice of IP will affect the efficiency and stability of the server. Static IP servers are stable and reliable, and are suitable for long-term deployment and service access; dynamic IP servers are more flexible and low-cost.
