Summary

Sigma Soft SRL

Romania · AI-generated

business rumania small

SIGMASOFT is operated by Sigma Soft SRL.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries like r202ev255.sigmasoft.ro and 81-181-203-126.sigmasoft.ro.
  • The AS announces 512 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.

Notable

  • The RDAP registrant ABUSE ICI LIR for the netname SC-SIGMA-SOFT-SRL aligns with the registry holder SIGMASOFT SIGMA SOFT SRL, confirming consistent ownership.
  • The inventory consists of a single contiguous /23 block, representing a compact and focused address allocation.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
