IP addressing is covered here in the video below, found on YouTube.
Take ten minutes to watch it and you'll speak like a geek in no time ... more to the point
- you'll understand that mysterious 'ip address' you come across from time to time
- you'll see how clever IP addressing is, how it enables a 'packet' of information to find a 'host' (or computer) anywhere on the Internet.
Also, when we tried the trace route command, Laura asked about EMMAN.net - just who are these mysterious names the the command reveals?
EMMAN Ltd is a company: it is owned by 8 Higher Education institutions in the East Midlands. Each one is connected to EMMAN's network via a very fast fibre optic cable, and thence to 'SuperJANET', a national HE network, and thence to the rest of the internet. The actual cables are leased from BT and ntl, two telecommunication companies. The 'tracert' command reported that our message had travelled via one of their servers. Hope that helps!
