America Runs out of Internet Addresses

Fibre optics
Today, the American Registry for Internet Numbers (ARIN) ran out of spare IP addresses. This is almost exactly three years after the European registry (RIPE NCC) and leaves Africa as the only region still able to freely supply addresses. From today, apart from a few exceptional cases, ISPs, data centres, etc. will be unable to get any new IPv4 addresses. What will this mean for ICT managers of British schools?

Show users

Over the years, the Iceni's hierarchical grouping system has proved itself to be extremely flexible and easy to understand.

However, it has always been limited in how fine-grained the configuration can be - since the configuration is applied to whole groups, adjusting the configuration for a single user required a group to be created just for that user.
