Summary

Nomura India Services Pvt Ltd

India · AI-generated

business finance corporate

NOMURAINDIA-AS-AP is operated by Nomura India Services Pvt Ltd.

What it's used for

  • The address space carries corporate infrastructure for Nomura, with netnames EU-MAP-6 and EU-MAP-4 registered to NOMURA HOLDING AMERICA INC, and NOMURATOKYO-AS-TK registered to NOMURA INDIA SERVICES PVT LTD.
  • The AS announces 7936 IPv4 addresses across 14 prefixes with 4 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.

Notable

  • Registrants are consistent with the announcer, showing NOMURA HOLDING AMERICA INC for most prefixes and NOMURA INDIA SERVICES PVT LTD for the 180.149.200.0/24 block.
  • The address inventory is finely subdivided into multiple /22, /23, and /24 blocks within the 163.124.0.0/16 range, typical of site-by-site corporate segmentation.

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 1,778 prefixes, as published 2026-10-20. 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.
