Hong Kong server

1.
What is "Hong Kong native IP"
• Definition: Native IP usually refers to the public IPv4/IPv6 address directly announced by the local ISP or the local independent autonomous system (ASN).• Hong Kong native IP: issued by Hong Kong ISP or Hong Kong ASN, the route starts from Hong Kong and does not go through third-country NAT or tunnel.
• Difference from shared/proxy IP: non-proxy, non-tunnel, routing table indicates real geographical location.
• Technical features: Usually BGP direct connection, less NAT, and more formal reverse DNS settings.
• Impact on business: Directly related to delays, compliance, probability of being blocked, and geographical restrictions.
2.
Why many people choose Hong Kong native IP
• Low latency: The average ICMP latency from mainland China to Hong Kong is usually in the range of 20-40ms, which is better than European and American nodes.• More stable routing: BGP direct connection reduces transit, and the packet loss rate can be reduced to less than 0.1%.
• Compliance and access: Used for cross-border business, it can reduce the probability of being misjudged as an agent, and the domain name whitelist rate is higher.
• SEO and content distribution: Search engines and some services will refer to IP ownership, and Hong Kong IP is more friendly to Hong Kong/Southeast Asian users.
• Business needs: Payment, games, short video acceleration and other scenarios that require native geographical location determination.
3.
Association with server/VPS/host/domain name/CDN
• Server selection: Many VPS providers will label "Hong Kong native IP" or "HK BGP". When choosing, look at the ASN and exit link.• Domain name and DNS: Domain name resolution to Hong Kong native IP can be accessed through geographic DNS or Anycast optimization.
• CDN cooperation: Using the native IP as the origin on the Hong Kong node can reduce the return-to-origin delay and improve the return-to-origin success rate.
• Certificate and reverse DNS: Native IP makes it easier to make PTR records, which facilitates email services and compliance review.
• Payment/Cost: Native IP usually costs slightly more, and bandwidth billing needs to be weighed against peak bandwidth demand.
4.
DDoS defense and the practice of Hong Kong native IP
• Risk point: Native IP is directly routable, and traffic attacks will directly hit your computer room or VPS.• Defense strategy: upstream traffic absorption (cloud protection), placing CDN or WAF in front of the origin site, speed limiting and black and white lists.
• Recommended architecture: CDN (Anycast) + cloud DDoS cleaning + local firewall policy (iptables/nftables).
• Real data: An e-commerce company witnessed a DDoS peak of 600Gbps, which dropped to a normal peak of <0.5Gbps after cloud cleaning.
• SLA and monitoring: Recommended 5-minute alarm, BGP community black hole support and network bandwidth redundancy scheme.
5.
Real cases and server configuration examples (including data tables)
• Case background: A game agency needs to provide low-latency login and recharge for Hong Kong and Macao users, and chooses Hong Kong’s native IP VPS as the node.• Server configuration examples: Below are three common configurations with measured latency/bandwidth data (average values).
| Plan | Configuration | Bandwidth | Average delay to Guangzhou | Monthly fee (USD) |
|---|---|---|---|---|
| Lightweight | 1 vCPU / 1GB RAM / 30GB SSD | 100Mbps share | 30ms | 8 |
| Standard type | 4 vCPU / 8GB RAM / 160GB SSD | 500Mbps exclusive | 22ms | 60 |
| High defense | 8 vCPU / 16GB RAM / 500GB NVMe | 1Gbps exclusive + cloud cleaning | 20ms | 300 (including DDoS) |
• Case results: After adopting "standard + CDN back-to-source + cloud cleaning", the success rate of recharge transactions increased from 93% to 99.6%, and the median login delay was reduced by about 15%.

Select suggestions and implementation steps
• Needs assessment: Determine the target user's geographical location, number of concurrent connections, and whether the business is sensitive (payment/email/game).• Test verification: Purchase a short-term package or trial, and test the packet loss and bandwidth of the target area through mtr/traceroute/iperf3.
• Architecture design: The origin site uses Hong Kong’s native IP, front-end CDN and cloud protection, supplemented by dual network card backup and BGP multi-routing.
• Operation and maintenance monitoring: Enable real-time network and application monitoring, set traffic threshold alarms and automatic switching strategies.
• Cost trade-off: Compare the cost and performance of native IP and tunnel/acceleration solutions, and choose the combination that best meets your business goals.
