Summary

Si.TEK Informatica Srl

Italy · AI-generated

business italy small-isp

The AS handle SITEK is held by Si.TEK Informatica Srl.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netnames IT-SITEK-20190102 and IT-SITEK-20141114 and the reverse DNS entry asr920b.si-tek.net.
  • The network announces 2048 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small-scale access or business network rather than a transit provider.
  • As an IT consultancy and connectivity provider, the traffic consists of client web/API endpoints and office connectivity services.

Notable

  • The registrants for both announced prefixes are Si.TEK Informatica Srl, matching the AS holder.
  • The address inventory consists of two /22 blocks, one in the 139.28.0.0/16 range and one in the 185.77.0.0/16 range.

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 1,784 prefixes, as published 2026-10-19. 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.
