About this network

Every reverse name carries a thirty-two character hexadecimal label, different for each address.

What it's used for

• A county government's network. 512 addresses in one IPv4 prefix, 74.43.150.0/23, one observed BGP neighbour, and no IPv6 announced.

Notable

• The block is netname FRONTIER-COMMUNICATIONS, registered to Verizon Business.
• All three sampled addresses answered, each as 74-43-150-128 and so on, followed by a long hexadecimal string, then ip.frontiernet.net.
• The strings differ per address: e3b0753e076b95380749346feb70ba42 for one, a different one for the next.

Interesting

• A thirty-two character hex label is the length of a common hash. The provider is generating reverse names that include an identifier derived from something about the subscriber or the address, and publishing it. Hashing it hides what it was made from while still giving every address a stable, unique token that anyone can collect.
• That token is more useful to an outsider than a plain name would be. It does not say who the customer is, but it does let anyone tracking these addresses tell them apart and notice when one changes hands.
• The netname naming one carrier while the registrant names another is the residue of a sale of customer accounts, and the reverse zone still answers under the older brand's domain.
