ARIN provides the latest word that we need to move to IPv6… will anyone heed the warning? (Does anyone care?)
Continue Reading: ARIN provides the latest word that we need to move to IPv6… will anyone heed the warning? (Does anyone care?)NetworkWorld is running an article today that talks about the announcement from ARIN (the American Registry for Internet Numbers) of the ARIN Board resolution calling upon ARIN to no longer be “neutral” in the IPv4 vs IPv6 space and instead work to actively encourage migration to IPv6.
For those not aware, ARIN is a non-profit organization that allocates IP addresses within North America and is one of the five Regional Internet Registries that allocate IP addresses on behalf of the Internet Assigned Numbers Authority (IANA).
Think of it this way… let’s say you start a business and want to get an Internet connection where you can run your own web server. You need a public IP address, so you are going to contact an Internet Service Provider (ISP), set up service, get an address, etc., etc. If you are in North America, the public IP address you are going to get will have been allocated to your ISP by ARIN. ARIN, in turn, was given blocks of IP addresses to give out by IANA, who is ultimately responsible for all IP addresses. So it looks something like this:
IANA -> ARIN (and the other RIRs) -> ISPs -> You

Skype raises public chat limits to 150 – but why do I see 200 in a chat room?
Continue Reading: Skype raises public chat limits to 150 – but why do I see 200 in a chat room?Today Skype announced that you could now have up to 150 people in a public chat session. They had quietly rolled this out a bit ago, but I only noticed then because I monitor and participate in a couple of Skype public chats that focus on new releases/features of Skype and development issues.
There does, though, seem to be a continuing puzzle around discrepancies regarding the actual limits. Ask any 4 people in a Skype public chat to type “/info” on the command line and relay the result… and you’ll probably get four very different answers. I just did that in one public chat (Update: it was the “Skype Developer community public chat“) and, as shown in the graphic, showed a total of 201 people in a chat session… with the limit theoretically being 150! Someone else in the chat did the same command and showed 122 people. At various times in the past, we’ve done similar tests and found that there’s a very wide range of numbers.
One has to wonder… is this something about the peer-to-peer “cloud” that makes up the Skype infrastructure? Is this a convergence issue? i.e. over time the numbers will converge to a…
