Summary
Eolas
hosting isp business infrastructure
A customer's brand is readable in one reverse name, alongside the word blog and a number.
What it's used for
- A hosting provider, now part of a large carrier group. Eleven IPv4 prefixes and one IPv6
/32announced from France, nine thousand addresses, across sixty-two observed BGP neighbours.
Notable
- Five blocks use a netname of country code, company and allocation date; three more carry a hosting brand written as a phrase in the local language; two belong to a different company entirely under its own name.
- One answering address is an edge server numbered five in a zone named after the first letter of a classical alphabet.
- The other names a customer's brand, the word blog and a number, so a site's owner and its role can be read from the address.
- Eighteen addresses were queried for reverse DNS and two returned a name.
- The parent carrier appears in most registrant fields; the operating company's own team appears in all of them.
Interesting
- Sixty-two neighbours for nine thousand addresses is a well connected hosting network. The addresses are the product and the interconnection is what makes them worth buying.
- Naming customer sites in reverse DNS is convenient for the operator and an inventory for everyone else. Anyone can enumerate which brands a hosting provider serves without asking.
- Three separate brands across eleven blocks records a company that was bought and kept selling under its own names, which is normal in this market.

Reputation
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
