Summary
MailChimp
hosting media business
Every block carries one netname that names the job: delivery. The reverse names spread the same machines across four different domains.
What it's used for
- An email marketing platform's sending network. 14,592 addresses across 26 IPv4 prefixes, with a single observed BGP neighbour and no IPv6 announced.
Notable
- Every block that resolved carries the netname
RSG-DELIVERY, registered toMailChimp. - Seven of eighteen sampled addresses returned a name, across four domains:
mail0.atl91.mcsv.net,mail254.atl171.mcdlv.net,mail254.suw16.rsgsv.netandmail133-254.atl131.mandrillapp.com. - The middle label is a site code with a number:
atl91,atl131,atl171,sea81,suw16,suw21,wdc02. - The AS handle is
THEROCKETSCIENCEGROUP, the parent company, which appears nowhere in the registrations.
Interesting
- Bulk email lives or dies on reputation, and reputation attaches to addresses. Spreading identical machines across four domains lets the operator separate its products in the eyes of every spam filter on the internet, so one customer's bad campaign does not poison the rest.
- The site codes name a city and then a number, which means several sending clusters per location. Segmenting by cluster as well as by domain gives even finer control over which addresses carry which traffic.
- One netname across 26 prefixes says the whole estate has one purpose. Most networks this size hold a mixture; this one holds outbound mail and nothing else.
- One neighbour is all a sender needs. Nobody has to reach these machines; they only have to reach everybody else.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
