Firstly, thank you for your patience as we tried kmeet/jitsi. Whilst a lot of it did work, and it has a number of advantages over zoom, I think we can conclude that it didn’t work for all of us. I plan to investigate big blue button and see if that is useful to us.
This month we look at IP (Internet Protocol) addresses, including both IPv4 and IPv6. The talk includes a brief description of IPv4 addresses, problems with IPv4, IPv6 addresses and current IPv6 status.
