The Long Road to IPv6

 September 22nd, 2013Sep 22nd, 2013      

There is a transition happening, albeit slowly, from IPv4 to IPv6, that is going to have an impact, but mostly on online gaming and other peer to peer services. Ever since the introduction of the Internet as we know it today, we have been using public IPv4 addresses to talk to people and to access content online. Unfortunately we have run out of IPv4 addresses as there weren’t enough to go around. An IPv4 address is a 32-bit number which is represented as 4 numbers separated by a dot (e.g. 192.168.0.1) – this provides roughly 4.3 billion addresses. In comparison, an IPv6 address is a 128-bit number which is represented as 8 groups of 4 hexadecimal digits separated by a colon (e.g. 2001:0db8:85a3:0042:1000:8a2e:0370:7334) – this amounts to approximately 48,000 quadrillion addresses (4.8 x 10^28) for each of the seven billion people alive in 2011.

Understanding PS3 NAT Types

After spending a little time investigating online gaming on the PS3, there appears to be a lot of conflicting information with regards to what NAT is and how the PS3 classifies your NAT type. Everyone who plays online seems to spend a lot of their time (instead of actually playing games) trying to achieve a different NAT type, or thinking their NAT type is why they keep getting shot.

NAT or Network Address Translation is something which people generally can’t avoid and has become the norm in computer networking. For a device to be able to access content on the Internet they need a public IP address. There aren’t enough public IP addresses (until IPv6 is fully embraced, which is still a way off) to give every one of your devices a public address which mandates a form of translation.
