Summary
Sinch Voice
telecom voice business
NEUTRAL-TANDEM is operated by Sinch Voice, formerly known as Inteliquent and Neutral Tandem.
What it's used for
- The address space carries telecommunications infrastructure, evidenced by netnames such as
IQNT-NET-BROAD-6andNEUTRALTANDEM-COM. - With 27,392 IPv4 addresses across 69 prefixes and only 8 observed neighbours, the network functions as an access or business network rather than a transit provider.
- Traffic from this AS consists of VoIP media and signalling, reflecting the operator's business in voice services and telecommunications.
Notable
- All registrants in the sample are listed as Inteliquent, inc., which aligns with the historical identity of the AS holder prior to its rebranding.
- The operator was originally Neutral Tandem, which merged with Tinet in 2010 and subsequently rebranded as Inteliquent before becoming part of Sinch.
- The inventory consists primarily of /23 and /22 blocks, with a single larger /21 block, indicating a finely subdivided corporate estate.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
