User:212.219.0.0

The 212.219.0.0/16 range covers a large number of academic and local government establishments connected to the JANET network. In some cases a local council's IP range will in turn feed primary and secondary schools as well as corporate systems. Care should be taken if blocking ranges to avoid inadvertently blocking other unrelated organisations.
