One of the best route servers I’ve ever used is: route-views.oregon-ix.net. So, to get started simply telnet to that hostname. You’ll see a prompt like this:

Next, simply type: show ip bgp x.x.x.x . Take a look at sample output below.

route-views>sh ip bgp 8.8.8.8

Using route servers is particularly useful to see if a carrier/company is announcing your prefix. Play around with it and have fun!
