[AfrICANN-discuss] IPv4's Last Day: What Will Happen When There Is Only IPv6?

Sat Apr 24 16:02:49 SAST 2010

It does get quite uncomfortable sitting back watching the counter run
out at http://ipv6forum.com/ :(

My considered opinion is that it would help end users much if AfriNIC
community supported end users with information, popularised, and
assisted more to use available, free IPv6 tunnel brokers - giving a
first-hand experience of the IPv6 internet? for example, "Freenet6
Tunnel is the most popular access service enabling users to seamlessly
connect to the IPv6 Internet. In addition to the services available
through this site, a list of other publicly accessible IPv6 services
are in the community forum," says
http://gogonet.gogo6.com/page/freenet6-services.

Would such a program already be existence? My apologies if it already
does for I was not aware of it.

kind regards,

Alex

>> the Middle East and Central Asia, the Asia-Pacific Network Information
>> Centre (APNIC) for Asia and the Pacific region, the Latin American and
>> Caribbean Internet Addresses Registry (LACNIC) for Latin America and
>> the African Network Information Centre (AfriNIC) for Africa.

>>
>> According to Jimmerson, there are now 20 /8s remaining in the IANA
>> pool, which makes it likely that ARIN will get more IPv4 address

>>
>> "In the ARIN region demand for IPv4 may have leveled off and slowed
