That's the whole idea of DNS, no need to worry about the IP address. And people remember names a whole lot easier than 12 digit numbers. Its the phone book of the Internet. You can do it, if its only for local hostnames and you host them yourself. But the client does cache IP resolved addresses too for a certain amount of time. So its only the first time resolving that takes a couple of milliseconds, the second time it should be cached locally (be that on disk or in memory).

Using the IP address could be a "poor mans" means of putting files that support a webpage on a "cookieless" domain, which is one way to speed up page loading. The key would be to be the one that controls the IP address and for it to be a dedicated IP for your website.

Back in the old days when I started using the internet, IP-addresses in URLs were very common. It was only later, with the emergence of www, that "vanity" domain names started to get popular. So, yes of course you can use IP-addresses :)
