Subject: Is there life after DNS?
Reply-To: address@hidden
Hi all,
did you ever ask yourself that question?
With 2369 domains we have the best root. We are the frontier. We
have to think
what comes after DNS.
ICANN does not face that frontier. They used to have 250 Domains
but they lost
one. No they are back to 249. They cannot go up to 250 again
because the
next domain they want to introduse is "xxx." and that gets
filtered and
accused on most servers they use because they are owned by
universities.
It just happened to me and several others on NANOG. :)
IPv6 will be a challenge. No normal human beeing thinks of typing
in IPv6
addresses. Cut and paste, maybe - but typing, no! IPv6 will break
DNS!
There are nameservers behind firewalls that dont allow tpc
connections to the
namesevers. IPv6 addresses will break packet borders and they will
finally
break these nameservers.
You dont need IPv6? Ipv4 is good enuf for you?
Joe and me, we have seen IPv9 working. Stay with your old IPv4
machines and let
governements decide what is good for you. Send your emails to the
governement
and let them decide what is spam. They are looking forward to
reading and maybe
forwarding or not your emails. Who needs to run a mailserver
anyhow. Dont you
think its a good idea of the goverment to close port 25 forwarding?
If you dont think so read on!
Today we have to worlds a host might live in. There are some good
guys running
servers running important machines with fixed addresses. They make
up the world
of DNS. Everybody can ask DNS for their addresses and maybe their
names.
And then we have hosts like yours and mine connected via NAT-
routers to dsl- or
cable-modems or to good old pots via good old modems. Whenever I
connect to the
internet I get a new ip. An ip that somebody else might have used
for sending
spam the I cannot use it for sending emails. An ip that nobody
knows not even me.
If I dont disconnect and reconnect my provider will do that for me
once every
24 hours. That is the world of P2P users and services like no-
ip.com .
How do these hosts know eachother? How do they find eachother. How
do they
connect? How do they identify?
There is live outside DNS. I have met them.
Before we had DNS there was /etc/hosts and there still is NIS. NIS
+ might have
become DNS but SUN has given up. It does not scale up.
Still there is P2P. It is losely connected to DNS by services like
no-ip.com
Does P2P really need static ip addresses?.
The DSLAM the concentrator and router I am connected to, manages
some 4K addresses.
To find echnaton.serveftp.com just try 4K ip addresses and you
have got me.
If only 100 hosts of those 4K possible addresses in the voicinity
of frankfurt on
main, germany had a P2P-nameservice running you would only have to
ask 40 addresses
to get me.
You got me?
Have a nice weekend
regards,
Peter and Karin Dambier
