Summary
Dialpad
business cloud communications sip
The AS handle DIALPAD is operated by Dialpad, Inc.
What it's used for
- The address space carries corporate infrastructure for a cloud communications platform, with netnames such as
DIALPAD-170,DIALPAD-209, andDIALPAD-AP-1identifying the registrant as Dialpad, Inc. - The AS announces 12,288 IPv4 addresses across 7 prefixes and 16 IPv6 prefixes, while maintaining 124 observed neighbours; this ratio of modest address inventory to high peering density indicates a transit-heavy role for a large-scale cloud service provider.
- Traffic from this AS consists of VoIP media, signalling, and API endpoints for Dialpad's AI-powered contact center and unified communications services.
Notable
- All registrants for the largest prefixes are consistent with the announcer, listing "Dialpad, Inc." or "Dialpad IP Admin" as the responsible party.
- The address inventory is subdivided into multiple blocks, including a /20 and /21 in the 170.10.0.0 range and a /20 in 209.127.0.0, reflecting a segmented corporate estate for a global SaaS provider.

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: 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.
