Summary

Sigma IT Infrastructures Development Co.

Iran (Islamic Republic of) · AI-generated

business iran portal

The AS handle is SIGMA and the holder is Sigma IT Infrastructures Development Co. (Ltd.).

What it's used for

  • The space carries enterprise portal and e-service infrastructure, evidenced by the netname IR-SIGMA-20190513 and reverse DNS entries pointing to sepanta.net.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS consists of web and API endpoints for enterprise portals and online services, consistent with the operator's business of designing and developing digital platforms in Iran.

Notable

  • Registrants align with the announcer for the primary block, with Sigma IT Infrastructures Development Co. (Ltd.) listed for 45.15.200.0/22, while the secondary block 85.133.198.0/24 is registered under Public Role with netname SEPANTA.
  • The address inventory is compact, consisting of one /22 and one /24, with no IPv6 prefixes announced.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
