Summary

business legal corporate internal
The AS handle FFHSJ is held by Fried, Frank, Harris, Shriver & Jacobson LLP.
What it's used for
- The address space is registered under the netname
BLK198-15-ANSwith registrantVerizon Business, indicating the space was originally allocated to a telecommunications provider before being associated with the law firm. - The AS announces a single IPv4 prefix,
198.80.208.0/23, comprising 512 addresses, with 0 IPv6 prefixes. - With only 3 observed neighbours, the low neighbour count relative to the address block suggests an internal corporate estate rather than a transit or access network, consistent with a single organization's site segmentation.
Notable
- The RDAP registrant
Verizon Businessdiffers from the current AS holder, Fried Frank, which may reflect historical allocation or leasing of the address space prior to the firm's acquisition or assignment of the AS. - The inventory consists of a single contiguous /23 block, representing a finely subdivided internal estate typical of a large corporate entity managing its own network infrastructure.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
