Unclassified APNIC
Summary
Metaswitch Networks
telecom business enterprise
Three companies in one registrant field, and the acquisition chain shows in the netnames.
What it's used for
- A communications software company's network. Three IPv4 prefixes and four IPv6 prefixes announced from the United States, with three observed BGP neighbours.
Notable
- One registrant field names an operations team belonging to the company's acquirer, followed by a third company entirely, joined by a semicolon.
- The other two blocks are registered to the company itself, under netnames that share a six-letter root, one bare and one with a type word appended.
- A third netname marks the protocol version in the label, on a block that carries no IPv6 at all.
- The four IPv6 announcements tile one allocation at two lengths, splitting a
/46into pieces. - One of nine sampled addresses answered, with an opaque ten-character host label under the company's own domain.
Interesting
- A registrant field that names an acquirer's operations team rather than either company is a record updated by whoever now answers the phone. It is more useful operationally than the company name would be, and it makes the field useless for identifying who owns the space.
- Marking the protocol version in a netname is redundant, since the block's format already says which it is. It only makes sense as a way to distinguish a v4 record from a v6 record in a system that keeps both, and the record here does not.
- An opaque host label discloses less than the descriptive names elsewhere in this range, which for a vendor whose software runs carrier voice platforms is the right trade.

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 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
