• In theory the speed limit of GPRS is 115 kbps, but in most networks it is around 35 kbps.
• This mechanism was even worse in terms of failure rates, and some 40% of Teredo connection attempts were observed to fail.

A feature of IPv6 is that every device can create a unique link-local address based on the MAC address of the device. It works by inserting 0xFFEE into the middle of the MAC address.

Officially, we have to say the FCC (and similar agencies in other countries) have been granted the power – by the people – to regulate the radio spectrum, and you really shouldn’t disobey them. Notice the phrasing in that last sentence, and draw your own philosophical conclusions.

And just like converting an IP address into binary, you can do the same thing with a subnet mask. Interestingly, the external IP address assigned to your router by your ISP is probably part of a subnet, which might include many other IP addresses for nearby homes or businesses.

How can I make localhost resolve to 127.0.0.1 instead of ::1?

NAT has been increasingly used for IPv4 networks to help alleviate IPv4 address exhaustion. The total pool, however, is sufficient for the foreseeable future, because there are 2128 (exactly 340,282,366,920,938,463,463,374,607,431,768,211,456) or about 3.4×1038 (340 undecillion) unique IPv6 addresses. 6to4 may be used by an individual host, or by a local IPv6 network.

Also, network upgrades of features are available with certain operators. With these enhancements the active 192.168.0.50 round-trip time can be reduced, resulting in significant increase in application-level throughput speeds.
