The difference between native IP and non-native IP

Source and allocation method:

Native IP (local IP): usually a public IP address directly assigned to a server or host by an Internet Service Provider (ISP). It is a real public IP with the same registration location and actual use location. Such an IP address is unique globally and can be directly routed from the Internet to the corresponding server.

Non-native IP (broadcast IP/shared IP/NATed IP): This type of IP address is not directly provided by the local ISP, but is obtained indirectly through technical means such as network address translation (NAT), proxy server or IP broadcast. Non-native IP may mean that multiple devices share a public IP address, or that the IP address can be used normally, but its registration location does not match the actual use location.

Independence and accessibility:

Native IP: Each server has an independent and unique public IP, and the outside can directly access the server without any forwarding or conversion.

Non-native IP: Since it may be shared, it is impossible to guarantee that the outside can directly access a specific server, and it needs to rely on NAT mapping rules or other intermediate layer processing.

Applicable scenarios and limitations:

Native IP: Suitable for services that need to provide services directly to the outside world and are not restricted by geographical location, such as website hosting, game servers, remote office, etc., and in some applications that have strict regional requirements for IP addresses, such as regional unlocking of streaming services, network service verification in certain specific regions, etc., native IP will have more advantages.

Non-native IP: Suitable for cost-sensitive scenarios with low demand for direct public network connection, such as devices in the internal network accessing the public network through NAT, or for lightweight applications that do not require end-to-end direct communication.

Performance and stability:

Native IP: Usually has better performance in network transmission speed, stability and reliability because there is no additional NAT conversion overhead.

Non-native IP: In the case of shared IP, it may be affected by NAT conversion efficiency, resulting in a decrease in network performance, especially in application scenarios with high concurrency or high real-time requirements.

Query and identification:

You can query the WHOIS information of the IP address to check whether the registered location of the IP address is consistent with the actual server location, so as to determine whether an IP address is a native IP.

Website Optimization and Recognition:

For SEO and website optimization, native IPs may sometimes have certain advantages, especially when search engines consider geographical relevance. At the same time, some service providers or platforms only accept native IPs in specific regions, and non-native IPs may not meet such requirements.
