Summary
Bandwidth Inc.
voip telecom enterprise
Bandwidth is a US communications platform provider, selling voice, messaging and emergency calling as APIs to other companies rather than to end users.
What it's used for
- Carrying the voice and messaging infrastructure behind other people's products. Most netnames read
BWCOM-NETOPS-BLK, marking the space as network operations rather than customer assignment.
Notable
- The reverse DNS names the site:
208.94.157.255.ptr.den.dashcs.netand208.94.158.254.ptr.atl.dashcs.net, withdenandatlfor Denver and Atlanta. The domain isdashcs.net, from Dash Carrier Services, the carrier entity Bandwidth operates under. - Only 9,000 addresses across six prefixes. A voice platform needs very little address space compared to its traffic, because a call is a small amount of state on a media server rather than a per-user address.
- One block sits in RIPE rather than ARIN, registered to UK Bandwidth Limited under the netname
UK-BANDWIDTH-20190523— the company's British arm, assigned in May 2019.
Interesting
- Naming POPs by airport code in reverse DNS is a habit inherited from the telephone network, where every switch had a location code. It survives because it is genuinely useful: when a call has a problem, the traceroute tells you which city to look in.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
