Summary

Sysmex

United States · AI-generated

business research enterprise

One /22, one netname, and a registrant that ends with the job title of whoever filed it.

What it's used for

  • A medical diagnostics manufacturer's network. 1,024 addresses in one IPv4 prefix, 208.70.240.0/22, two observed BGP neighbours, and no IPv6 announced.

Notable

  • The block is netname SYSMEX, registrant Sysmex; Administrator.
  • The netname, the AS handle and the company name are all the same word.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • A semicolon followed by a generic job title is a contact record that was never filled in properly. The registry wanted a person or a team; it got the word for whoever happens to hold the account, which is honest about how these things are actually maintained.
  • Every identifier here is the same six letters, which is what a single-word company name buys you. There is no abbreviation to get wrong, no counter to disambiguate, and no history of mergers hiding in the strings.
  • A company that makes blood analysers sells instruments that sit in hospital laboratories and phone home for calibration, reagent ordering and fault reporting. One /22 with two upstreams is the far end of those conversations.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
