Network namespaces are useful for setting up containers or virtual environments. Each namespace has its own IP addresses, network interfaces, routing tables, and so forth. The default or global namespace is the one in which the host system physical interfaces exist. Namespace-specific address spaces can lead to problems when MySQL connections cross namespaces. For example, the network address space for a MySQL instance running in a container or virtual network may differ from the address space of the host machine. This can produce phenomena such as a client connection from an address in one namespace appearing to the MySQL server to be coming from a different address, even for client and server running on the same machine. Suppose that both processes run on a host with IP address  203.0.113.10  but use different namespaces. A connection may produce a result like this: In this case, the expected  USER()  value is  admin@203.0.113.10 . Such behavior can make it difficult to assign account permissions properly if the address from which an connection originates is not what it appears. To address this issue, MySQL enables specifying the network namespace to use for TCP/IP connections, so that both endpoints of connections use an agreed-upon common address space. MySQL 8.0.22 and higher supports network namespaces on platforms that implement them. Support within MySQL applies to: 994 •X Plugin. •The MySQL server,  mysqld . 7. To see your IPv6 address: 6.
