Summary

Morgan Stanley Management Service (Shanghai) Limited

China · AI-generated

enterprise legacy

MSMSL-AS-AP belongs to Morgan Stanley Management Service (Shanghai) Limited, the Chinese service entity of the US investment bank. AS7609 is a corporate network, not a provider network.

What it's used for

  • A single small allocation, 103.183.66.0/23, announced as the /23 and a covering /24. There is no reverse DNS on it, which is normal for a bank's internal and DMZ addressing.
  • The space serves Morgan Stanley's own offices and systems in Shanghai. It has no customers, no hosting tenants and no subscriber pools.

Notable

  • Financial-sector enterprise space. Traffic from these addresses is bank staff and bank systems, not consumers, and it should be geolocated to a corporate site rather than to a residential or datacentre pool.
  • APNIC's record for the autnum was created in March 2022, far later than the number's neighbours. AS7609 is a low number that has been reissued to a modern holder; it carries none of the early-internet pedigree that a four-digit ASN might otherwise suggest.

Interesting

  • The number sits in a stretch of the low-7600s dominated by 1990s-era Asia-Pacific research networks, universities and broadcasters. A 2022 assignment to a foreign bank's Shanghai back-office entity is a good reminder that APNIC recycles returned numbers, and that a low AS number is not by itself evidence of age.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
