Summary
CALGAH Computer Systems Management
hosting business infrastructure
The registrant field lists the same operations centre twice, once plain and once with a job title in front of it.
What it's used for
- A computer systems management company's network. 3,072 addresses across two IPv4 prefixes,
199.204.48.0/21and208.72.176.0/22, one observed BGP neighbour, and no IPv6 announced.
Notable
- Both registrants read as the company, then its operations centre, then that centre again prefixed with an administrator title, joined by semicolons.
- The netnames are
REDWARNINGCANADAandREDWARNING1, a brand the registrant name does not contain. - The AS handle is that same brand, without the country or the counter.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Three parts in a registrant string where two of them name the same team is a contact list that grew by addition rather than by editing. Nobody removed the general entry when the specific one arrived, and the registry has no opinion about duplicates.
- The brand appears in the AS handle and both netnames while the legal entity appears only in the registrant. Anyone searching for the company by trading name finds the network; anyone searching by the name on the paperwork finds the company.
- One upstream for two blocks in different ranges, one of them from an early allocation, is a small operator that has been around long enough to hold old space and never needed a second path.

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 1,782 prefixes, as published 2026-10-16. 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.
