Unclassified APNIC
Summary
Navajo County
government business isp
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 toVerizon Business. - All three sampled addresses answered, each as
74-43-150-128and so on, followed by a long hexadecimal string, thenip.frontiernet.net. - The strings differ per address:
e3b0753e076b95380749346feb70ba42for 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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
