As a high-performance network solution, IP dedicated lines offer advantages such as exclusive bandwidth, low latency, and high stability, playing a critical role in the infrastructure of industries like finance, cloud computing, and multinational enterprises. Below, we delve into the practical value and usage specifications of IP dedicated lines.

I. Definition and Core Features of IP Dedicated Lines

An IP dedicated line is a technical solution that provides enterprises with end-to-end exclusive network resources through physically or logically isolated private channels. Unlike ordinary broadband shared networks, it has the following characteristics:

Dedicated Physical Link: IP dedicated lines transmit data via specialized media such as fiber optics or MPLS, effectively avoiding public network congestion, with latency controllable within 10ms.

Guaranteed Bandwidth: It offers committed rates (e.g., 100Mbps, 1Gbps) and maintains stable transmission during traffic spikes, making it ideal for applications like video conferencing and real-time transactions.

High Security: Data is transmitted through closed channels, reducing the risk of interception or tampering by over 80% compared to the public internet.

II. Typical Application Scenarios

Financial Trading: Millisecond-level trading systems of securities firms rely on IP dedicated lines to achieve zero packet loss, ensuring fast and accurate transactions.

Multinational Collaboration: Enterprises can build internal networks between branches via IP dedicated lines, enhancing data transmission efficiency by 300% and facilitating cross-border operations.

Cloud Service Access: Cloud platforms can achieve secure hybrid cloud connectivity through dedicated line gateways (e.g., NAT-type dedicated lines), meeting enterprises’ cloud service requirements.

III. Six Key Considerations for Using Dedicated Lines

(1) Network Topology Planning and IP Conflict Avoidance

When designing a private network, build dedicated lines based on a custom private network, as default system networks do not support dedicated line access. If a cloud host is already connected to another network, replace the network first to allow the system to reassign IP addresses and avoid conflicts. The mapped IP in NAT configuration rules must not overlap with the CIDR of the dedicated line gateway’s network and should avoid broadcast addresses (e.g., 255.255.255.255) and D/E class address ranges. A single dedicated line gateway supports up to 100 IP mappings; apply for quota expansion if exceeded.

(2) Routing and Device Management

Routers are critical for dedicated line connectivity—shutting down a router will interrupt the line. Deploy dual routers for redundancy and set up automatic power-failover mechanisms. Integrate proxy IP services (e.g., ipipgo) for intelligent routing optimization and traffic splitting, reducing cross-border transmission latency by 60% while avoiding platform risk-control throttling.

(3) Security Protection Strategies

Cloud hosts on dedicated lines require manual port opening, as default firewall policies block unauthorized access. For example, database services need port 3306 unlocked with restricted source IP ranges. Encrypt sensitive data via SSL tunnel encryption (e.g., AES256) to enhance security and prevent eavesdropping. Professional providers like ipipgo offer automatic certificate rotation with a loss rate of less than 8%.

(4) Bandwidth and Performance Monitoring

Enterprises should reserve 30% bandwidth redundancy for peak loads (e.g., e-commerce promotions, live streaming). Use tools like Zabbix to monitor bandwidth utilization and trigger alerts when thresholds exceed 80%. Configure intelligent load balancing with primary-backup nodes to auto-switch when primary node latency exceeds 150ms, ensuring service continuity.

(5) Compliance and Cost Control

For cross-border operations, use local residential IPs (e.g., ipipgo covers IP resources in over 240 countries) to avoid compliance reviews due to geographic IP anomalies. Optimize costs with a hybrid billing model (“pay-as-you-go + reserved capacity”) by releasing idle bandwidth during off-peak hours.

(6) Fault Diagnosis and Emergency Response

Use the traceroute command to locate network breaks. If hop counts increase abnormally or packet loss exceeds 5%, contact your ISP immediately. Prepare backup 4G/5G channels for quick recovery—manually switch to them during outages to minimize downtime losses.
