Cool, DNS works. From a networking perspective, you're golden!
But why did he get different IP addresses?
Like Paul said, Google uses a bunch of IP addresses for each of their
services. When I run a continuous DNS lookup of gmail.com, I get
multiple addresses, mostly neither of the two listed above.
If you have access to a Linux box, this command "watch -d dig gmail.com"
will resolve gmail.com to one or more IP addresses every 2 seconds and
will highlight the differences between one iteration and the one before
it. Let it run for awhile and you're likely to see a good handful of
different IP addresses.
