During the IESG/IAOC Plenary at IETF 71, we are going to turn off
IPv4 support on the IETF network for 30 to 60 minutes. We will
encourage the audience to use the Internet and determine which
services that they have come to take for granted remain available.
If there is no gateway somewhere with an IPv4 address, we will do very
little.
We performed this experience last month at an IPv6 training in
Nouakchott (Mauritania). The students had only IPv6 connectivity to
the Internet. As Mark Andrews said, we were not able to even resolve
the names with AAAA records because the root does not have IPv6. In
the end, we cheated by adding a DNS gateway (BIND on a machine with an
IPv4 address) and a Web gateway (Apache with mod_proxy on a machine
with an IPv4 address).
I cheat the other way by letting the nameserver see the
AAAA's for the root servers that have IPv6 addresses.
e.g.
zone "f.root-servers.net" {
type master;
file "master/f.root-servers.net";
notify no;
allow-query { localhost; };
};
master/f.root-servers.net:
@ 3600 IN SOA drugs.dv.isc.org. marka.isc.org. 1 3600 1200 604800 3600
@ 3600 IN NS drugs.dv.isc.org.
@ 3600 IN A 192.5.5.241
@ 3600 IN AAAA 2001:500::1035
The question is what do we wish to test. A IPv6 only world
or a IPv6 only network with access to proxies etc. to allow
access to IPv4 resources indirectly.
