TODO: change name to "Network Architecture" and change content to more generally describe how the univerersity network works, with specifics about VTLUUG's setup. Direct to [[Infrastructure:Network]] with talkinga about specific IPs and mention that link a lot throughout the page when we fix the wiki so this isn't confused [[Infrastructure:Network]] and move Historic section to [[Category:Deprecated]] and leave a link here

=== IPv4 ===

Most Internet-connected computers communicate using Internet Protocol version 4, usually abbreviated IPv4. IPv4 assigns an address to each computer. These addresses are 32 bits long, and can be written as a period-separated list of four numbers from zero to 255. One example would be 192.168.1.1, an address commonly given to home networking equipment. The 32-bit address space of IPv4 allows for about four billion addresses. Given that there are over six billion people on the planet, it's clear that these addresses will eventually run out. It turns out that due to the way these addresses are allocated in blocks, we actually already have run out.
