Do I have static IPv6 addresses?
For the first time, I logged into my Comcast Business account, went to the "Manage Services", "Internet", page, and noticed a link to "View Static IP", so I clicked on it.
It brings up a page that not only shows the static IPv4 addresses I know very well, but also "Static IPv6 Information", which is a "/56" address that starts with "2603:3024:".
Are these address really static? Can I depend on them not changing when our modem loses power?
And, also important, will Comcast make a PTR record with these addresses?
