I suprised that you dont have satalite interent meow. Uses the satalite connection for downstream and the phone connection for upstream.
IPv4 is what we use here in the states and most of europe.
IPv6 is where we are going as they use that in asia and some places in europe. The big difference is the number of available IP addresses.
With IPv4 there are enough IP addresses for half of the people on the planet, 4,294,967,296 total. Not all of those addresses are usable either.
0.0.0.0
10.x.x.x
127.x.x.x
192.168.x.x
172.16 through 31.x.x
240 through 255.x.x.x
replace x with any number (0 through 255) and those are the private/military/broadcast addresses.
Obviously not everyone has internet access nor the need for a public IP. So toss out 3-4 billion people with no access at all. Of the 4 billion left who do have internet access, how many also have a cell phone? 2 phones? A game console hooked up? Internet connected TV or DVD? 1 PC? Laptops?
With IPv6, you will have aproximately 340,282,366,920,938,000,000,000,000,000,000,000,000 ip addresses. More than enough for everyone to have 6 or 7 devices. I think someone worked out the math to see that there will be 100 ip addresses per square foot of land on the planet. As far as when will we change over? How long did japan have HD TV before we did? 10 years? more?
Sorry I wasnt on when you were having problems. GL with avast.
