The machine serving this page. A gateway is the HTTPS front door to the nodes that hold the chain: it terminates TLS, rate-limits, and proxies the chain API to an archival node so a browser can read the chain without running one.
The routes above answer from whichever archival node this gateway picks. To query one
named node instead, put its IP in the hostname — dots become dashes, and an optional
-p<port> chooses the API port:
ip-192-168-1-100.this-gateway/api/v1/node/info
Only nodes on this gateway's allowlist answer; anything else is refused rather than proxied, so the hostname cannot be used to reach arbitrary hosts.
