legal corporate business
The AS handle APORTER is held by Arnold & Porter Kaye Scholer LLP.
What it's used for

KS-US1for the law firm, indicating a dedicated corporate network rather than a public service provider. - The AS announces a single IPv4 prefix, 192.203.254.0/23, comprising 512 addresses, with no IPv6 prefixes in inventory.
- With only 3 observed neighbours, the low ratio of addresses to peers suggests an internal corporate estate with limited external peering, consistent with a private business network.

- The inventory consists of a single contiguous /23 block, representing a finely subdivided internal estate typical of large corporate entities managing their own infrastructure.

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 1,773 prefixes, as published 2026-10-13. 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.
