Summary
Swift Online (SwiftMail Communications)
legacy hosting isp
AS9830 (SWIFTONLINE-AS-AP, "SWIFT ONLINE BORDER AS") is registered in India to SwiftMail Communications Limited, based in Chennai, operating under the Swift Online name. Registry directories classify it as an ISP; the announced inventory tells a more specific story, and it is worth reading carefully.
What it's used for
RIS sees 36 IPv4 prefixes carrying 9,216 addresses and no IPv6, announced through 3 BGP neighbours. Almost all of it is 202.91.64.0/19 split into individual /24s — announcing a block one /24 at a time, rather than as a single route, is a deliberate choice and is characteristic of address space that needs to be reputationally separable — plus a few unrelated /24s (160.20.5.0/24, 163.227.198.0/24, 103.239.65.0/24). One sampled address carries the operator's own newmail.swift-online.com, but most resolve to algorithmically-generated hostnames under many unrelated third-party domains (patterns like reminder5.<word>202.<domain>), including at least one offshore gambling domain. That is the classic look of address space used for bulk-email or affiliate-marketing sending pools, whether run by the operator or leased out to customers doing it.
Notable
- Marketing and inventory diverge. The AS is filed as an ISP, but there is no eyeball rDNS and no subscriber pattern in the space. Treat "ISP" here as a registry category, not a description of the traffic.
- The per-
/24deaggregation across a single/19is the operational signature of a sender-reputation strategy: when one/24gets blocklisted, the rest keep working. - No IPv6 is announced.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
