About this network

MUFG Securities EMEA PLC (MUSI) — the European investment-banking arm of Japan's Mitsubishi UFJ Financial Group, based at Ropemaker Place in the City of London.

What it's used for

• The bank's own network. Its main holding is 162.11.0.0/16 (netname UKMFIL), a legacy class-B block registered directly to MUFG Securities EMEA at its London address, announced as a summary route over Colt and Lumen circuits.
• It also originates 193.104.4.0/24, registered as BTMU-NET to the former Bank of Tokyo-Mitsubishi UFJ entity — a fossil of the group's pre-merger naming.
• No customer or subscriber space anywhere: this is trading, settlement and corporate infrastructure for one financial institution.

Notable

• Roughly 65,000 addresses for a single bank is unremarkable for a legacy /16 holder. Financial institutions were early, well-funded internet adopters and many hold class-B space they will never fully route.
• The LEGACY status on the inetnum means the block predates the RIPE NCC's allocation policies and is held under the legacy-resources arrangement rather than a normal LIR allocation.

Interesting

• The registry preserves the group's merger history better than its own website does. MUSI, UKMFIL and BTMU-NET are three different eras of naming for the same institution, all still live in RIPE objects.
