About this network
LHSYSHU belongs to Lufthansa Systems Hungária Ltd., the Budapest arm of Lufthansa's airline-IT subsidiary. The RIPE descr field is literally its street address — Neumann János u. 1/E, H-1117 Budapest — which is a common quirk in older RIPE objects and not a separate organisation.
What it's used for
Corporate and development-site connectivity for an aviation IT provider. Lufthansa Systems builds and operates software for airlines (flight planning, crew and operations systems), and this AS multihomes a single /24 of that company's own space.
Notable
An enterprise end-site network, not a provider. At 256 addresses it is one of the smallest autonomous systems in the low-numbered RIPE range — the AS exists for redundancy and address independence, not scale.
Interesting
The handle is a compact clue worth decoding: LHSYS for Lufthansa Systems, HU for the Hungarian entity. Names like this are why registry handles are the first thing to expand when identifying an AS.
