Sometimes it's slightly simpler to show rather than tell.
The CIDR Report is a publicly accessible compendium of BGP routing announcements. Mind that this isn't the entire Internet, or even entirely current, though it's a very large and generally current version of it. One of the complications is that you're only seeing the routes the CIDR Report itself is aware of (there may be others, though generally those will be small/obscure).
But if you want to know what "the Internet" is, this is pretty much it: a bunch of rules for routing data.
(There are a maximum of 2^16 == 65,536 autonomous systems possible under BGP, at least until those counters are extended. What happens under IPv6 may be a bit of a mess....)

As for BGP, Border Gateway Protocol:

Edit: There's 4 billion and change as ASNs are now 32 bit, see: https://news.ycombinator.com/item?id=15915417
