AS15092 STAR2STAR - Sangoma US Inc.
Hosting ARIN
Summary
Sangoma US (Star2Star)
telecom business hosting
A netname that spells the whole block out, under a handle that names the company it used to be.
What it's used for
- A voice-services network. Four IPv4
/24blocks and one IPv6 prefix announced from the United States, with three observed BGP neighbours.
Notable
- The AS handle is
STAR2STARwhile the registrant on every block that resolved is Sangoma, so the handle preserves the acquired brand and the address records carry the acquirer. - One netname is
RGTS-TELEK-IP-66-43-105-0: two abbreviations that belong to neither company in the record, the stringIP, and the full network address with its dots turned into dashes. - Another block sits under
STAR2STAR-COMMUNICATIONS, the old name again, in full this time. - Two of the four registry lookups failed, so nothing can be said about who holds those blocks.
- Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- Writing the entire network address into the netname is the most literal version of a habit that runs through this whole range. It is accurate on the day it is written and it survives the reassignment that makes it wrong, because nothing in the registry checks a name against the object it names.
- Three identifiers for one company, in three fields, is the ordinary cost of an acquisition. Anyone matching this network by name has to know all three strings mean the same operator, and the record never says so.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
