isp residential india ntt

NCINSPL-IN is operated by NTT Communications India Network Services Private Limited.

What it's used for

  • The address space is registered under the netname NCINSPL-IN with registrants identified as NTT COMMUNICATIONS INDIA NETWORK SERVICES PRIVATE LIMITED administrator.
  • The AS announces 135680 IPv4 addresses across 141 prefixes and 35 IPv6 prefixes, while maintaining 64 observed neighbours. This ratio of address volume to peering partners indicates a role as an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of the inventory align with the announcer, specifically NTT COMMUNICATIONS INDIA NETWORK SERVICES PRIVATE LIMITED administrator.
  • A subset of prefixes, including 142.79.224.0/21 and 159.117.152.0/21, carries the netname LEE with registrant Manager Admin, which differs from the primary NTT identity.
  • The inventory consists of a mix of /19, /20, and /21 blocks, with the largest being 123.108.32.0/19 and 124.153.96.0/19.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,773 prefixes, as published 2026-10-13. 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.
