Summary
RingCentral
business voip cloud telecom
The AS handle RC-COLO1 is held by RingCentral Inc.
What it's used for
- The address space carries RingCentral's cloud communications infrastructure, evidenced by netnames such as
RC-PRO-3,RC-PRO-5,US-RINGCENTRAL-20010720, andRINGCENTRALINC-AP. - The AS announces 16,896 IPv4 addresses across 24 prefixes and 1 IPv6 prefix, while maintaining 173 observed neighbours; this high neighbour count relative to the address inventory indicates a transit-heavy role for a large-scale enterprise network.
- Traffic from this AS consists of VoIP media and signalling, web/API endpoints, and branch backhaul for RingCentral's global cloud-based phone and messaging services.
Notable
- All registrants in the RDAP data align with the announcer, consistently listing RingCentral Inc or RingCentral, Inc.
- The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, reflecting an internal corporate estate with site-by-site segmentation rather than a single contiguous allocation.

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.
