What it's used for
- The address space carries residential and business access traffic, evidenced by netnames such as
DELDSL-INandDELTEL, and reverse DNS entries likeptr-203-110-93-254.deldsl.net. - The AS announces 6,912 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants are largely consistent with the announcer, with most prefixes registered to
IRT-DELDSL-IN, though103.242.224.0/22is registered toIRT-IRINN-INand103.142.18.0/24toIRT-THSIN-IN. - The address inventory is subdivided into multiple smaller blocks, including several /24s and /23s, alongside larger /21 and /22 allocations, reflecting a segmented internal estate for different service tiers or regions.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
