About this network

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-ANS with registrant Verizon 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 Business differs 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.
