Business and enterprise customers can use branded nameservers

[Zenexer]

Business and enterprise can use branded nameservers. The branded nameserver IP addresses will match those the standard nameservers, so they're easy enough to find. Zone files typically include glue records for nameservers. Here are the first 10 in the com zone file:

NS1.STORMBLAZE A 173.245.58.51
NS1.GLOBO-CHEM A 173.245.58.51
NS1.BLACKSTONEHOSTING A 173.245.58.51
NS1.DBSDATA A 173.245.58.51
NS1.INALIAS A 173.245.58.51
NS1.IDEARTTE A 173.245.58.51
NS1.PHASE-7 A 173.245.59.142
NS1.HIPPERS A 173.245.58.51
NS1.FLASHSTOCKS A 173.245.58.51
NS1.TERA-KSA A 173.245.58.110

As such, using dig + grep is inadequate; many of Cloudflare's largest customers will go undetected.

Here are lists of com and net domain names that point to Cloudflare nameservers, taken from glue records in the latest zone files:

• com.txt
• net.txt

Attached is a list of com/net domains that use branded com/net nameservers. It's been run through LC_ALL=C sort -u, so each domain only appears once.

It goes without saying that this list is just based on nameservers, and is therefore still affected by #67.
