Autonomous system
AS13057 Esplanaden 50
Unclassified APNIC
Summary
A.P. Moller - Maersk
enterprise business infrastructure
The AS handle is a street address and nothing else, with no company name in it at all.
What it's used for
- The network of a Danish shipping and logistics company. 256 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The AS handle is recorded as
Esplanaden 50. - The single prefix is
193.163.240.0/24, netnameDK-APMOLLER1. - Registry contacts are an administrator role, the company, and an abuse role.
- Three addresses were sampled and none returned a name.
Interesting
- Several holders in this range put a street address after their name in the handle. This one has dropped the name entirely, so the field that identifies the network says only where its owner's door is. Anyone querying the handle gets a postal address with no way to tell whose it is without following the registry reference.
- That habit dates the record. AS handles were originally free text and were often filled in by copying whatever the registration form had asked for last, which was frequently the holder's address. The convention of using a short mnemonic came later, and this record predates it.
- A global shipping company announcing a single /24 through one neighbour is not running its operations here. This is a small piece of public-facing space; whatever the business actually depends on sits behind addresses that are never announced.

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 1,779 prefixes, as published 2026-10-21. 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.
