Summary
Morgan Stanley Management Service (Shanghai) Limited
enterprise legacy
MSMSL-AS-AP is Morgan Stanley Management Service (Shanghai) Limited, the Shanghai entity of the American investment bank Morgan Stanley. AS7653 is a corporate network, not a service provider.
What it's used for
- In-house connectivity for Morgan Stanley's Shanghai operation. The AS announces a single small block,
103.183.66.0/23, registeredMSMSL-CNdirectly to the company through APNIC. - Banks run their own ASNs so that a site can be multi-homed across carriers without depending on any one of them. That is the whole purpose here: a few hundred addresses, announced for resilience rather than reach.
Notable
- Enterprise address space. An address in AS7653 belongs to a bank's corporate estate. There are no customers, no subscribers and no hosting behind it, and it should never be read as Chinese consumer or datacentre space just because the registry country is
CN. - The block is a recent APNIC allocation out of
103.0.0.0/8, so the AS number and the addresses are of very different vintages: the number is a 1990s-era registration, the space is modern.
Interesting
- The low AS number is the interesting part. It is far older than the
103/8addresses it now carries, which is a good illustration of why an AS number's age says nothing about the age of the prefixes underneath it.

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.
