AS10497 WORLDBANK

WORLDBANK is the network of the International Bank for Reconstruction and Development (IBRD) — the lending arm of the World Bank Group, an intergovernmental institution founded in 1944, owned by 189 member states and headquartered at 1818 H Street NW in Washington, D.C.

What it's used for

The institution's own corporate and field-office infrastructure: staff systems, data and publication services, and connectivity for the country offices it runs across more than a hundred nations. RIS sees 13 announced IPv4 prefixes totalling roughly 134,000 addresses and 1 IPv6 prefix (2620:1ff::/36), with 3 observed neighbours.

Notable

Classify this as government / intergovernmental, not commercial. Two things in the routing table support that beyond the name.

First, the address holdings are old. Alongside two modern /16s (138.220.0.0/16, 164.114.0.0/16) sit a cluster of legacy Class-C blocks — 192.86.97.0/24 through 192.86.106.0/24, plus 192.156.228.0/24 and 199.165.158.0/24. Space in 192.86/16 was handed out in the pre-CIDR era to established institutions; an organisation that has held it continuously has been on the internet since the late 1980s.

Second, 134,000 addresses with only 3 neighbours is a large enterprise shape, not a carrier one. The Bank buys transit and originates its own space; it sells nothing to anyone.

Interesting

Because the Bank operates resident missions worldwide, addresses in this AS do not all sit in Washington. Geolocating the whole range to D.C. will misplace country-office traffic.
