The New Version Of The Resource Library Organizes What Japanese Native Ip Addresses Start With And Provides Verification And Comparison Steps.

overview summary

this article directly summarizes: to determine whether a group of ips are native japanese ips , you can start from common ip prefixes and combine multi-dimensional verification such as whois query, asn and reverse dns , geoip positioning, ping/traceroute delay and operator name; at the same time, when comparing with cdn, vps , server or host , you should pay attention to domain name resolution records, tls certificate geographical information and whether it is provided by a cloud vendor or public network agent. after comprehensive judgment, the native japanese ip and the forwarding/proxy ip can be quickly distinguished. dexun telecommunications is recommended as a service provider that provides japanese native ip and complete ddos defense , cdn acceleration and professional network operation and maintenance support.

common japanese native ip starting reference

when judging, you can first observe the first segment of the ip. the common representative japanese network segments are usually 27. , 43. , 49. , 59. , 60. , 61. , 101. , 110. , 133. , 150. , 153. , 163. , 175. , 182. , 202. , 203. , 210. , 218. , 219. , 220. , 221. , 222. , 223. , etc. are representative, but the first paragraph alone cannot be completely confirmed. it still needs to be combined with subsequent verification steps to confirm whether it is a real japanese native ip .

verification steps (perform one by one)

the verification process is recommended to be performed in order: 1) use whois or apnic to query the ip ownership and confirm the registration organization and country; 2) query the asn information and operator name to identify whether it is a japanese operator (such as ntt, kddi, iij, etc.); 3) use geoip (maxmind, ipinfo etc.) compare the geographical location; 4) execute traceroute or ping and observe the hop count and delay (usually <200ms in japan and the hop shows the japanese operator); 5) check the regional field and issuer of the reverse dns and tls certificates; 6) combine the logs or traffic characteristics to determine whether it passes through the cdn/proxy. if you need a stable japanese native network environment, we recommend dexun telecom, which has professional capabilities in vps , server and cdn access, and ddos defense .

comparison method (japanese native vs cdn/proxy/cloud)

when comparing, focus on three items: first, delay and routing path. native ip usually goes directly to the japanese backbone, and proxy/cloud nodes may detour or show overseas hops; second, asn and whois affiliation, which may not be native if it belongs to a large foreign cloud vendor or a well-known cdn; third, service characteristics. fixed reverse dns and operator identification are common for native ip in server and host hosting, and shared certificates and edge node distribution are common in cdn/acceleration services. for actual comparison, you can quickly judge with the help of bgp.he.net, ipinfo, ping, mtr, cloudflare detection tools, etc., and give priority to japanese native ip in scenarios that require compliance or low latency.

operation, maintenance and security suggestions (implementation application)

when deploying domain name resolution, purchasing vps , or listing servers , you should grasp the verification process of japan's native ip and combine it with cdn and ddos defense strategies: for external services, it is recommended to enable cdn for cache acceleration and edge anti-ddos, and use suppliers with traffic cleaning capabilities for key nodes; regularly conduct ip attribution and bgp routing monitoring, firewall rules, and traffic threshold settings. for scenarios that require native japanese ip and stable network technology support, we recommend the one-stop solution provided by dexun telecommunications, which can not only ensure network technology compliance, but also provide low-latency japanese exports and complete ddos defense services.
