education research hosting
The reverse names live under a domain that is the AS number itself.
What it's used for
- A training network. One IPv4 prefix and one IPv6 prefix announced from the United States, two hundred and fifty-six addresses, through one observed BGP neighbour.
Notable
- The AS handle runs together a shortened word for information security and a shortened word for education, and the netname repeats it exactly.
- The holder line is a company name that shares no words with either.
- All three queried addresses answered, and every name has four parts: the word for an address with the last part appended, the first three parts of the address in reverse order, a three-letter label for a reverse record, and the domain.
- That domain is the two letters for an autonomous system followed by this number, under a commercial suffix.
Interesting
- Registering a domain named after your AS number and hanging the reverse zone on it means the naming survives any change of company name, brand or business. The number is the one identifier that cannot be taken away.
- Writing the address partly forwards and partly backwards inside one name is unusual. The last part leads, then the first three follow in reverse, which reads as a template built to match the shape of the reverse lookup zone rather than the shape of the address.
- A holder name and a handle that share nothing is a company operating under a working title.

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.
