Summary
Net2Phone (IDT Corporation)
enterprise legacy
NET2PHONE is registered to IDT Corporation of Newark, New Jersey, and carries the network of its Net2Phone subsidiary — a cloud-communications and VoIP provider, and one of the earliest companies to commercialise voice over IP.
What it's used for
- The infrastructure behind Net2Phone's hosted PBX, SIP trunking and contact centre services, riding IDT's global carrier network.
- Reverse DNS on its routers resolves under
inet.n2p.com, with names likear2-ewr1-…— ewr being Newark, where IDT is headquartered.
Notable
- The footprint is unusually large for a voice provider — well over 200,000 IPv4 addresses across roughly a hundred prefixes — and includes legacy blocks such as
206.20.0.0/17, originally registered to Internet Online Services. IDT's address holdings accumulated across an earlier era of ISP and telecom acquisitions. - The bulk of the space carries no reverse DNS, so it does not read as a subscriber access network; it is a carrier's own service infrastructure.

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 1,772 prefixes, as published 2026-10-15. 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.
