Summary
Tim Stallard
research ipv6 uk
The AS handle STALLARD is held by Tim Stallard.
What it's used for
- The space carries a single IPv6 prefix,
2001:678:634::/48, with no IPv4 addresses announced. - The inventory consists of 1 IPv6 prefix against 15 observed neighbours, a ratio that indicates a transit or peering role rather than a large access network.
- Traffic from this AS is associated with educational and research activities, as indicated by the operator's self-identification in peering databases.
Notable
- The registry holder and AS handle both identify Timothy Stallard, confirming the individual ownership of the autonomous system.
- The address inventory is minimal, consisting solely of one IPv6 block, which fits the profile of a small-scale research or personal network.

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: 446 networks and 1,852 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.
