How To Assess The Network And Operational Capabilities Of Native IP Providers For Vietnamese Servers

1.

Network connectivity and latency testing

- Key points: Ping and traceroute measurements of target Vietnamese IPs from multiple test sites (Shanghai, Guangzhou, Singapore, Los Angeles, USA).
- Indicator recommendations: focus on average RTT, jitter, maximum packet latency, packet loss rate, and sample loss rate for at least 24 hours of continuous sampling.
- Tool recommendations: Comprehensive evaluation using mtr, ping, traceroute, speedtest-cli, and iperf3.
- Criteria: Local (within Vietnam city) RTT should be < 10ms; Neighboring countries (southern China/Singapore) should have an RTT of < 40ms; Cross-ocean (US West Coast) < 200ms is preferable.
- Tip: Observe whether the route hop count stops at a single fault node (such as frequent packet loss on intermediate lines) to assess link redundancy.
- Example measurement (excerpt): From Shanghai to a native IP in Vietnam, the 24-hour average RTT = 28ms, maximum packet loss = 0.8%, routing stable, no transnational black holes.

Verification of BGP/ASN and IP resource authenticity

- Verification steps: Check the target IP's WHOIS, routing announcements, and ASN (using bgp.he.net, whois.cymru, etc.).
- Focus: Whether it is a "native IP" (i.e., a prefix in the provider's own announcement), or only a resale/rental IP range.
- Risk warning: Resale IPs may be misused or linked to historical abuse records, affecting email delivery and trustworthiness.
- Criteria: Priority is given to suppliers with independent ASNs or long-term stable BGP announcements; Check the announcement time and number of prefixes.
- Example data: A certain alias IDC "VNH-01" announcement prefix: 203.113.0.0/20 (ASN AS45899), announced for 3 years, with no history of being blacklisted on a large scale.
- Recommended action: Use the following table to compare the candidate vendor's base routing information (sample table in paragraph 4).

Bandwidth, throughput, and packet loss performance (including iPerf/traffic tests).

- Key verification: Assess link quality based on peak bandwidth, long-term bandwidth utilization, and outbound congestion ratio.
- Testing method: Use iperf3 for single-stream and multi-stream tests, testing TCP and UDP separately, and recording bandwidth, latency, and packet loss.
- Indicator threshold: For BGP public network hosts, a single connection is expected to stably reach more than 70% of the line's nominal bandwidth; Long-term packet loss < 1%.
- Practical Case: VNH-01 data center single 1Gbps port measured peak single-stream TCP = 750Mbps, multi-stream concurrency average of 4 channels = 910Mbps, packet loss = 0.2%.
- Equipment inspection: Confirm whether the switch ports and uplink fiber are 10G/40G aggregated, and whether there are traffic shapings or SLA restrictions.
- Recommendation: Require suppliers to provide traffic curves and peak statistics screenshots for the past 30 days to verify if they match the promises.

4.

SLA, monitoring system, and operation and maintenance response

- SLA content: clarifying network availability (e.g., 99.95%/month), recovery time (MTTR), compensation mechanism, and monitoring alert responsibilities.
- Monitoring capabilities: Real-time alerts are required (including links, routes, port errors, disk, CPU, memory, processes), and API/log provision.
- Operation and maintenance response: verify work order response times (work orders/phone/emergency routes), and differences between workdays and holidays.
- Verification method: Simulated fault submission of work orders, recording response time and processing quality; Request historical fault notifications and repair records.
- Example metric: VNH-01 promises network availability of 99.9%, average ticket response time = 12 minutes (urgent), MTTR historical average = 45 minutes.
- Recommended clauses: Contract should specify key SLAs and penalty rules, clarifying responsibilities and upstream and downstream collaboration processes when DDoS occurs.

5.

DDoS protection and security protection capabilities

- Feature list: Whether cleaning platform (on-premise/cloud), cleaning bandwidth, cleaning policies (protocol/port/rate limit) are provided.
- Cleaning capability quantification: Focus on vendors' maximum cleaning bandwidth (e.g., 10Gbps, 40Gbps or higher), concurrent connection limits, and pure TCP/UDP hybrid protection capabilities.
- Testing and History: Request to review historical DDoS attack events, cleanup success rates, false kill rates, and recovery times.
- Configuration example: VNH-01 protection platform: edge cleaning 40Gbps + local black hole/rate limit; Historical record of largest cleanup instance: 21Gbps SYN+UDP hybrid attack, cleaned until available.
- Protection policies: supports ACL, blacklist and whitelist, GeoIP shielding, rate limiting, connection tracing, and application layer rules (Web Application Firewall).
- Recommendation: Sign dedicated DDoS SLAs for critical business (websites, APIs, emails) and require regular drills and reports.

Real case analysis and server configuration examples

- Case Background: A cross-border e-commerce company deployed a product warehousing site in Vietnam, requiring native IPs and low-latency interfaces to support payment gateways.
- Issues and evaluation: Before selecting a supplier, compare latency, packet loss, DDoS cleanup, and maintenance response from three Vietnam IDCs.
- Configuration: Final listed model is: Intel Xeon E-2288G 8C/16T, 32GB DDR4, 2x1TB NVMe, 1Gbps port (10Gbps uplink optional); Operating system: CentOS 7 + Docker-based applications.
- Test results (sample table): The table below compares the key indicators of three suppliers to facilitate decision-making.
- Effectiveness and recommendations: After selecting suppliers, continuously monitor and sign monthly reports and emergency contacts with them; Dual BGP backups are performed for critical resources to prevent single point failures.
- Future improvements: It is recommended to deploy a CDN for static acceleration combined with WAF to reduce origin exposure and bandwidth pressure.

supplier	average RTT (Shanghai)	24h packet loss	BGP prefix/ASN	DDoS maximum cleanup	SLA availability
VNH-01 (alias)	28 ms	0.2%.	203.113.0.0/20 / AS45899	40 Gbps	99.9%
VNH-02 (alias)	35 ms	0.9%.	45.126.32.0/22 / AS56021	10 Gbps	99.5%
VNH-03 (pseudonym)	22 ms	0.1%.	118.69.0.0/18/AS13654	80 Gbps (cloud collaboration).	99.95%

Conclusion and Procurement Recommendations

- Comprehensive evaluation points: Five core indicators: network connectivity, BGP authenticity, bandwidth performance, operations response, and DDoS capability.
- Select priority: If latency is sensitive, prioritize vendors with low RTT and near-node redundancy; If safety-sensitive is important, prioritize those with strong cleaning capabilities and a proven track record.
- Contract Points: Specify SLA, DDoS cleanup commitments, routing change notices, IP ownership certificates, and data preservation clauses.
- Preventive measures: It is recommended to have dual data centers or dual BGP access, use CDN+WAF combined protection services, and conduct regular stress and DDoS drills.
- Final reminder: Keep all measurement data and communication records during the assessment process to serve as the basis for future liability determination and claims.
- Contact advice: Before signing, require real traffic testing and emergency drills during the probation period (7–14 days) to verify operation and protection levels.
