Re: IPv6 Test Pages for Fortune 500 and Top 100 web sites are back

[Giorgio Bonfiglio via NANOG <nanog () nanog org>]

Hey Owen,

some data didn't add up to me so I ran some tests... Although the 
description says you check for both apex and www, I don't think the 
results reflect that.

ups.com, amazon.com, salesforce.com, oracle.com and others all have AAAA 
on www. and indeed have their website on www, but are flagged as red/red 
in your report.

Now - granted - the apex redirect is important, but in cases where all 
URLs over the internet are under www, marketing material is under www, 
etc - the only case where someone would hit the apex "ups.com" is when 
manually typing it in the browser and forgetting the www.

Such websites might not be green, but aren't even red?
