short answer -- yes it's normal
longer answer -- DNS stands for Domain Name Server. while you can ping www.yahoo.com and you can ping its IP address (209.73.186.238), there are a limited number of IPs available for usage on the internet.that's just how things got setup. now, inside of an ISP they can have any IP address that they want. example--at my house I have the ip range as 110.120.130.***. but my home network is completely autonomous meaning anonymous to any other network including my ISP's. if you were to ping one of my websites, www.dropzonecycling.com for instance, you would see an IP address of 69.91.6.7 which isn't even close to my home network address range. due to the multiple DNS on the internet you could browse to http://69.91.6.7 and get to www.dropzonecycling.com but not likely due to having a shared server w/ several websites. the router looks up the domain in its DNS table and then forwards the request to my server which in turn looks at the domain name and says ok that is in folder X and sends the info in folder X to the requesting address.
