A10H
research education ipv6

What it's used for
- The space carries research and educational traffic, as indicated by the PeeringDB classification of "Educational/Research" and the netname
A10H. - The AS announces 256 IPv4 addresses and 9 IPv6 prefixes, with 17 observed neighbours. This ratio of modest address space to a significant number of peering partners suggests a specialized research network rather than a large-scale commercial provider.

A10H LLCmatches the AS handle and netname, indicating consistent ownership. - The address inventory is dominated by a large IPv6 allocation, including prefixes as large as /41, alongside a single /24 IPv4 block.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
