Unclassified ARIN
Summary
Sierra Tel Internet
isp telecom infrastructure
Two prefixes, one upstream, and a reverse name that says broadband twice in a row.
What it's used for
- A mountain-region telephone company's internet service. 16,384 addresses across two IPv4 prefixes, with a single observed BGP neighbour and no IPv6 announced.
Notable
- Both blocks,
64.118.96.0/19and76.9.64.0/19, carry the netnameSTI, registered toSierra Tel Internetwith aNetwork Operations Centerand anAbusecontact. - Five of six sampled addresses returned a name. Four read
76-9-72-0-rt-broadband.broadband.oakhurst.sti.net; one reads64-118-104-0.static.sti.net.
Interesting
- The word broadband appears twice in one hostname, once as a suffix on the address label and once as the subdomain below it. Two generations of naming were composed rather than replaced, and the redundancy is now permanent.
- The
rtin front of it marks the router, and the town sits one level up. Read the name backwards and you get provider, town, service, device, address: an entire troubleshooting path in a single string. - One block is called static and the other is called broadband, which is a distinction between what a customer bought rather than what the address is. Business lines and residential lines land in different subdomains.
- Two
/19s and one neighbour is the smallest viable shape for an independent ISP. The AS number exists so the operator can change upstreams without renumbering every customer, and nothing else about the record is more complicated than it needs to be.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
