But it fails to do so. You have an undisclosed number of AXFR rejections leading to an unknown number of servers. What you're surveying are DNS servers whose parents allow promiscuous AXFR---basically, whose parents are old, badly managed sites. You're missing a huge number of 3LDs. My survey a year ago (http://cr.yp.to/djbdns/dns1.html) located 487828 different IP addresses for 599366 DNS server names. This is far more than the 100581 found by your broken survey mechanism. ---D. J.
