Most of the people on this list do not operate a national backbone. This aggregation technique is just fine if you really do have geographical diversity of nameserver location inside your AS. I'm not sure why anyone would go to the trouble of making it appear that their nameservers are in the same room when they are not. Priori had nameservers at PAIX and at Erols in Fairfax County, VA. But if a network does not have geographical diversity inside their AS then all of this /32 aggregation magic is for naught. If national backbones look like this: NS0.VERIO.NET 126.96.36.199 NS1.VERIO.NET 188.8.131.52 NS1.SPRINTLINK.NET 184.108.40.206 NS2.SPRINTLINK.NET 220.127.116.11 NS3.SPRINTLINK.NET 18.104.22.168 NS.CW.NET 22.214.171.124 NS2.CW.NET 126.96.36.199 NS3.CW.NET 188.8.131.52 NS4.CW.NET 184.108.40.206 then why wouldn't all ISPs look like this? NS1.EXAMPLE.COM 192.0.2.17 NS2.EXAMPLE.COM 220.127.116.11 NS3.EXAMPLE.COM 18.104.22.168 instead of the minimalist slapdash technique NS1.EXAMPLE.COM 192.0.2.44 NS2.EXAMPLE.COM 192.0.2.45 It's not hard to find an ISP in another state or another country to trade secondary DNS. And when the backhoe cuts a major fiber link in your area used by all three of your upstream providers, the world will know that you still exist. If you use the minimalist slapdash technique the world will think that you've gone out of business. -- Michael Dillon - E-mail: [email protected] Check the website for my Internet World articles - http://www.memra.com
