When you resolve an Akamaized hostname, the magical Akamai domain name system will magically respond with the IP addresses of at least two "optimal" Akamai servers. (They might not be "closest" because Akamai also takes into account things like server load, but they usually will be close - network wise.) This is frequently a server in the same ISP as the end user, especially in the US.
So, while you can do a dig on an Akamai hostname to get the IP address, also doing things like ping, or HTTP GETs, require you to resolve the hostname and go through the same resolution process. (Akamai cannot tell if you are doing an HTTP get, or a ping, or an FTP, or what when you do the resolution.)
In almost all cases, to use Akamai's service (i.e. be a customer), you need to have one or more Akamai hostnames associated with your web page, streaming server, etc. in some way.
Back to your question, as for permission, I am not the correct person to answer that question. However, they are public web servers, and they are designed to let anyone do HTTP downloads of the web content on them, so I know that is allowed.
Thank you for your interest in Akamai. :) >Adi -- TTFN, patrick P.S. What's wrong with pinging MS? :p P.P.S. Akamai uses its own products (hint-hint-dig-www-akamai-com-hint).
