At present, in the southern region, applying for telecom static IP address services can be done through telecom operators or through telecom ISP access providers. We are a telecom ISP service provider that provides 4M telecom static IP, 8M telecom static IP, 10M telecom static IP, 20M telecom static IP, 30M telecom static IP, and 50M telecom static IP. We can provide suitable external IP address services based on user needs, bandwidth size, and the required number of external IP addresses, according to the application layer of the client computer room. We also handle the application of telecom public IP addresses. If the client does not have high bandwidth requirements for the application layer, we only need a fixed IP address service, which requires IP authentication and server. An IP address is required, VPN devices require an IP address, and email servers need to be assigned one external IP address, all of which can be applied for. There is a public IP address service that can be upgraded on dial-up fiber optic lines, with a minimum speed of 4M bandwidth. The annual cost is over 8000 yuan, averaging around 666 yuan per month for IP address cost. The application time is within 24 hours to apply for a public IP address, install services, and have a free trial period of 3-5 days. If a larger fiber optic service is needed, it will be over 30M and the construction period will take more than 15 working days. If a dedicated fiber optic line is needed, it cannot be used for trial. As the construction of one fiber optic line requires at least one year of contract period, the construction cost is already over 60000 yuan per year, including construction costs, labor costs, and fiber optic cable costs.
