Do you utilize the IRR, have an as-set, and put all customer AS/CIDR's 
into the IRR?  I've honestly never heard from LVL3 about our 
advertisements.  Other providers have varied from just needing a web form, 
email, phone call, or those combined with faxed LOAs.  The latter gets 
very annoying...but maybe it is the way it should be.
