Summary

City Online Services

India · AI-generated

isp residential india cable

CITYON-AS-AP is operated by City Online Services Ltd.

What it's used for

  • The address space carries residential and business internet services, evidenced by netnames CITYON and CITYONLINE-IN across the majority of announced prefixes.
  • With 10,240 IPv4 addresses and 13 observed neighbours, the ratio suggests an access or eyeball network providing last-mile connectivity rather than a transit provider.

Notable

  • Registrants are consistent with the announcer for most prefixes, listing DIRECTOR CITYON and IRT-CITYON-IN, though one prefix (103.168.177.0/24) is registered to MANAGING DIRECTOR under netname SVB.
  • The inventory consists of six IPv4 prefixes and six IPv6 prefixes, including a large /19 block and several /24s, indicating a mixed estate of legacy and newer allocations.

Reputation

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: 436 networks and 1,771 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.
