Words mean what people use them for. Sure it's technically only 65534/65535 of an ISP, but that's not a very useful way to communicate with people about the issue.
If you are not allowed to run server, they are WSP (Web Service Provider) not ISP.
But if you are OK with ISP not providing internet, I'm sure you are fine with unlimited limited or throttled after x, 24/24 access between 9-5 and secured http page as long as there is a padlock favicon ...
> Words first mean what is written in a dictionary or encyclopedia.
Nope - this is an important difference between English and other languages. If what people say differs from what's in the dictionary, it's the dictionary that will change, not the people.
