My friend and I were driving down the road the other day when he turns to me and tells me that there is this website with links to great extranet security products for SharePoint and even links to SharePoint Training. I had to check this out for myself! “What’s the site?” I ask. “Oh, its http://216.215.157.252” To which I reply “Cool, I’ll look that up as soon as I get home… if I remember it!”
There is a reason we have DNS: it is so we can make things easier to remember. There was no way I was going to be able to remember http://216.215.157.252 unless I put it into a song (is 86753O9 going through anyone else’s head right now?)
You see, despite what Juliet may tell you, names are important. Sure a rose by any other name would still be as sweet, but the florist still gives me strange looks when I ask for a dozen #F80000 roses. You do not go around treating people as if they are storm troopers and asking "TK-421, why aren't you at your post? TK-421, do you copy?", so why would you treat your SharePoint web apps like they are storm troopers?
Give your SharePoint web apps names by configuring Host Headers.
