isp hosting colo legacy

TELNET-ITALY is Telnet S.r.l., an Italian operator and internet provider with offices in Pavia and on Via Caldera in Milan. It describes itself as an OLO and ISP doing hosting, housing, and colocation.

What it's used for

  • Business connectivity, and hosting and colocation in its Milan data centres, which sit in the Via Caldera technology cluster where many Italian carriers interconnect.

Notable

  • A business-focused provider. The address space mostly serves company circuits and hosted or colocated equipment, not household broadband.
  • Telnet was founded in Pavia in 1994, among the first companies in Italy to sell internet connectivity, and it is a founding member of the Milan Internet Exchange (MIX) and of AIIP, the Italian ISP association.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
