I think we all agree that CIDR is a good thing, I have no problems with it and feel that we should use it as best we can.
We all agree there.
problems that I see, yes I know this has been said before, it is getting harder and harder for the little guy to get IPs from the Nic.
We have the same harder and harder time getting addresses too.
Now that Sprint is saying that you now need a /16 to route over their network,
wrong. it is /18 in 207/8
I don't see the nic just handing out /16s like they did with the /19 or before that the /20s etc.. That is true, but with a good network plan and swib your current addresses you should be able to get a /18 on a new allocation if you can justify it. else get from an already aggregated block
And Just because I have nothing else to do, except work, sleep, work, internet, eat, work, sleep, I did some looking around.
me too, just none of that sleep stuff these daze ;-)
[21]/export/home/c/cnielsen> whois 208.0.0.0 Sprint (NETBLK-SPRINTLINK-BLKS)
Netname: SPRINTLINK-BLKS Netblock: 208.0.0.0 - 208.3.255.0
Here now shows that Sprint is getting a /15 from the nic and that they can now server more customers, move their ips around with little problem, etc. But what about some other ISP? Can they get a /15? Nope. But I bet you that if Sprint wanted to or even MCI for that matter, they could get a /14 or a /13 from the nic.
We have to justify all ip blocks just like anyone else. We maintain an excess of 90% utilization before asking for more.
How can we solve this problem? How can we make sure that everyone has equal access to IP addresses to make IP addresses usable around the Net, save on router memory etc? This is how I would do it.
Move into the 206.10.0.0 - 206.15.0.0
Any ISP/NSP that can provide a good network outline, showing not only how they plan to put into pratice but show their current setup, locations, etc. will be assigned a /16 in the range above. That would give about 1200 ISPs /16s.
Guess what. that is exactly how you get what you are asking for from the registry. In fact even if you can only justify a /19 now but have a good plan, a /18 or better is usually reserved for you and the /19 allocated. If you make good on your plan your /19 becomes a /18 etc.
