Unclassified ARIN
Summary
Gooflare
hosting research measurement
The handle says testbed, and there are fourteen IPv6 prefixes against a single IPv4 block.
What it's used for
- A network described in its own handle as a testbed. 512 addresses in one IPv4 prefix,
199.188.148.0/23, fourteen IPv6 prefixes, and two observed BGP neighbours.
Notable
- The AS handle is
GOOFL-TESTBED. - The IPv4 block is netname
SAL-309, registered to a company with a different name from the holder. - Every IPv6 prefix begins
2602:f83d:, split into sizes from a /43 down to a /48. - Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Announcing one range as fourteen separate prefixes of six different sizes, through two upstreams, is what a testbed looks like from outside. Nobody needs that many routes; somebody is exercising how announcements propagate, which sizes get filtered, and how the table reacts.
- Fourteen IPv6 prefixes against one IPv4 block inverts the usual ratio and fits the same reading. A network experimenting with routing does it where address space is cheap.
- Saying
TESTBEDin the handle is a courtesy to everyone watching the routing table. Anomalous announcements from an unlabelled network get investigated; from a labelled one they get ignored, which is what both sides want.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
