All IP addresses on a network must be unique except when anycast is used.

IPv4 addresses are classified into Classes A, B, and C.

The mask length of /24 can simplify network design.

Variable length subnet mask (VLSM) is often used for determining mask lengths to improve IP address efficiency.

Life cycle assessment (LCA) is a technique to check and analyze the software and hardware life cycles of devices on the live network. With LCA, specific measures are taken for products that will reach the end of sales, production, software update, or technical support, preventing life cycle-caused operation risks.

Software assessment & recommendation is a technique to assess and analyze all software platforms used by Party A in the service period. Based on the assessment result, this service can recommend a proper software version to prevent issues caused by known issues.

Configuration assessment & optimization is a technique to develop and periodically maintain device configuration profiles based on customer requirements. Based on the periodic software assessment & recommendation result, this service applies related software features to command lines in the recommended target version, implementing refined configuration management.

Network health check enables Huawei technology experts to review the rationality, security, and scalability of the network architecture based on industry-leading optimal experience, and to provide improvement suggestions based on the assessment result.
