Trump wants to Ban Internet?

Trump wants to Ban the internet to foil terrorism? Maybe a bit simplistic but I sort of agree with the idea.
I've argued that the internet is a wonderful tool for all criminals including terrorists. But no one can truly be anonymous there. To get on you need an IP address, much like a car number plate. All IP addresses relate to countries and are obtained from companies who own them. So if the authorities want to know who is saying what track the IP address down. EASY. Yes I know they try to hide, spoofing or using proxies, but also all internet traffic has to be routed. So just like Trump wants to Mu slims entering USA, then track the IP addresses as far as you can then where it stops the company routing it should be locked down. The message wool echo across the internet and the company's don't want to lose business. Maybe whole countries need blocking? Can be done, till they root out the criminals. It's not just Google,  Facebook, Microsoft to blame they just sit on the internet but they should too take down the vile information hosted. They should give up all information on the people behind the names used.
