Summary
Pulsar360
telecom isp business
Half its published names are addresses written backwards; the other half are numbered telephone systems.
What it's used for
- A voice and connectivity provider's network. 3,328 addresses across five IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.
Notable
- The blocks split into two groups by netname,
P360-1andP360-2, each covering a different part of the address space. - Eleven of fifteen sampled addresses answered, in two forms:
255-213-21-199.pulsar360.comandpbx1491.pbx.pulsar360.com. - The AS carries a first-seen timestamp of
2000-08-18T08:00:00, the start of the routing archive.
Interesting
- The first form is the address with its parts in reverse order, generated automatically for everything with no better name. The second is assigned by hand to a hosted telephone system, one per customer, each with its own four-digit number. You can read the company's product line directly out of its reverse zone: unremarkable connectivity, and phone systems it runs on the customer's behalf.
- Those system numbers run into the thousands and are not sequential across the sample, so the counter is global and has been running a long time. Numbering customers rather than naming them is what you do when there are too many to remember.
- Both netnames are the brand shortened to four characters and a number, which is the tidiest scheme in this part of the range and still tells an outsider nothing.
- Voice traffic is why there are two upstreams and no IPv6: calls break visibly when a path fails, and nobody has ever demanded a phone system be reachable over the newer protocol.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-23, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,779 prefixes, as published 2026-10-24. 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.
