AS12727 VIALIS Colmar, France
Residential RIPE Cable/DSL/ISP
Summary
Vialis
isp telecom government
A municipal utility in Colmar that also sells Internet access, holding two IPv6 /31s.
What it's used for
- Local access networking in Alsace. 15,360 addresses in five IPv4 prefixes, two IPv6 prefixes, and 43 observed BGP neighbours.
Notable
- Every block carries the same holder and the same contact,
VIALIS ADMINISTRATION RESEAUX. - The dated netnames run
FR-VIALIS-20000426,20090728,20110301,20111025and20131031. - The IPv6 announcements are
2a03:d600::/31and2a03:d604::/31. SEMin the holder name marks a société d'économie mixte, a company jointly held by a local authority and private shareholders.- Fifteen sampled addresses were queried and none returned a name.
Interesting
- A
/31is twice the standard IPv6 allocation, and holding two of them is an unusual amount of address space for a network serving one part of one French département. It also sits on an odd bit boundary, which means the reverse zones for it cannot be delegated as a single unit. - Municipal utilities make natural Internet providers, and the reason is trenches. An organisation that already runs gas, electricity or district heating under the streets owns the one asset a new entrant cannot buy, and adding fibre to an existing duct costs a fraction of digging for it.
- Five allocations spread across thirteen years, each one a step up in size, is the growth curve of a network that kept its customers. The public shareholding is why it could keep asking: the returns went back into the ground rather than out to a parent company.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
