You have to know what the IP address of your home machine is to even ping
it. There are a number of ways to do this, but the easiest is to use a
Dynamic DNS provider and a DDNS client. There are a number of these services
which service a small number of hostnames for free, but charge for more. The
three that come to mind are DynDNS.org, no-ip.com and ZoneEdit.com. You'll
need to set up an account with them as well as set up a client to keep your
DNS current so you can type in the hostname of your server at home and get
the correct (public) IP address at any given time.
Please note that 192.168.x.y and 10.x.y.z are not "routeable" IP addresses
and cannot be used over the internet. Also, please note that the free
version of VNC does not provide any encryption and only limited protection
against brute-force password guessing. It also doesn't protect against
"sniffing" of your session. Running VNC over the internet is a good way to
get your machine hacked, in my not-so-humble opinion.
To avoid this, you can either purchase the "personal" version of VNC or set
up a "tunneled" VNC session using something like Hamachi or SSH. You can
also use something like EchoVNC which would avoid having to configure
port-forwarding on your broadband router.
