About 1-ES FREE

1-ES serves Madrid from a single building, one of four fabrics A-Systems has carved out of a single 91.213.73.0/24 by giving each country a quarter of the block and its own IPv6 range. Madrid holds 91.213.73.64/26 with 2001:7f8:175::/64 and runs a payload MTU of 9000. 17 networks connect over 18 ports for 1.94 Tbps, all but one of them dual-stacked, and the membership reaches past regional carriers to Cloudflare, Valve and Hurricane Electric, the last on 400G. Ports are sold from 1G to 400G over single-mode fibre and cost nothing on this fabric.
