If an ALTO Server were to provide a global view of the whole internet,
wouldn¹t its PIDs be on the scale of Autonomous Systems AS¹s? Granted
not all AS¹s are public, and some could be combined. But aren¹t there
close to 60k AS¹s?
That¹s where I got the idea of 5,000 PIDs.
And what seems realistic now may not be realistic 10 years from now. How
long did it take to realize that ASNs had to be 32 bits, not 16?
And for that matter, I remember in the early days of defining domain
names, after we defined the important TLDs like .edu, .org, .net, .gov and
.mil, somebody suggested adding ³.com² just in case some commercial
enterprise wanted a domain name. Of course, we never expected more than a
handful of companies would take us up on that.
