Hosting ARIN
Summary
Vivio Technologies
hosting business infrastructure
One hostname answers for addresses in five different blocks.
What it's used for
- A United States hosting provider. 9,216 addresses across ten IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
sanguine5.viviotech.usis the reverse name for addresses in five separate prefixes.- A sixth address answers as
sanguine.viviotech.us, the same name without the number. - Eight blocks are netname
VIVIOTECH; one isABSG-04-01, registered to a different company. - One prefix's registry lookup failed, so nothing is known about its registration here.
Interesting
- The same name on the last usable address of five unrelated blocks is a gateway naming convention. Each block's router answers to the same host, because it is the same router, and the reverse zone for each was pointed at it individually.
- Naming machines after moods or humours rather than function is a hosting provider's habit from when the fleet was small enough to remember. The numbered sibling is what happens when the scheme outlives the first machine.
- Ten prefixes from ten unrelated ranges is space bought piece by piece as it became available, which is the only way to grow in IPv4 now. The single foreign netname is one of those purchases whose registration was never transferred.

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 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,771 prefixes, as published 2026-10-15. 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.
