Why are we currently undergoing a switch from ipv4 to ipv6?.

There are not enough addresses in IPv4 to support all of these devices of the lPv6 also allows for more secure communications between these already insecure devices

to change your username, you must:

1) make sure what the username you want to change to is allowed in this community

2) contact a administrator (for example, jaysl)

3) through pm, tell the admin what you want to change to

4) if the username is allowed, it will be changed in a matter of seconds (minutes at most)
