Unclassified RIPE
Summary
Chengjie Guo's Experimental Network
research experimental ipv6
GUO-AS is held by Chengjie Guo.
What it's used for
- The address space consists entirely of IPv6 prefixes, including
2a0a:6040:d600::/44and2a0a:6040:d610::/46, with no IPv4 inventory. - The AS announces 13 IPv6 prefixes and maintains 17 observed neighbours, a ratio consistent with a small-scale research or experimental network rather than a commercial transit or access provider.
- 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
GUO-ASmatches the AS handleChengjie Guos Experimental Network, confirming the identity of the operator. - The address inventory is finely subdivided into multiple /48 and /46 blocks within the
2a0a:6040::/44range, typical of an internal experimental estate.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
