# AS402801 NOC — noc.andrii.net > noc.andrii.net is the network operations site of AS402801 (ANDRII-NET), the network Andrii Co. runs to serve its own projects, including its notary platform. It publishes the network's facts and peering policy, and a looking glass: ping, traceroute, DNS and TLS checks run on request from Seattle, WA, US, AS402801, for a browser, a script or an assistant. Washington State customers: [andrii.co](https://andrii.co) · British Columbia customers: [andrii.ca](https://andrii.ca) ## What this is - [The network](https://noc.andrii.net/index.md): AS402801's prefixes, points of presence, exchanges, routing security and contacts - [Peering](https://noc.andrii.net/peering/index.md): the policy, the exchanges and how to peer - [The looking glass](https://noc.andrii.net/mtlg/index.md): every tool and parameter, and how to call them AS402801 announces IPv6 /48s carved from its own ARIN allocation and one IPv4 /24, carries no transit, and has no downstream customers. Its prefixes: `2602:f337:ed::/48`, `2602:f337:a5::/48`, `2602:f337:ac::/48`, `199.184.91.0/24`. Its points of presence: Seattle, WA, US; Amsterdam, NL. ## Calling the looking glass `POST https://sea.noc.andrii.net/api/1/{ping,trace,dns,tls}` with a JSON body of the parameters (at most 4 KiB). The answer is an NDJSON stream (`application/x-ndjson`): `{"t":"batch","seq":N,"ev":[…]}` lines of live events as they happen, then one `{"t":"done","result":{…},"quotas":[…]}` line whose `result` is the envelope (schema `lynceus/1`: `tool`, `id`, `started`, `finished`, `vantage`, `request`, and `result.runs`, one per family and, for DNS, per type, each with its `result`, or `skipped` or `error`). A refusal is one `{"t":"error","code":…,"reason":…}` line instead. Use `curl -N` so the stream isn't buffered. Measurements leave from Seattle, WA, US, AS402801. ```sh # five pings to example.net, in IPv4 and in IPv6 (two runs) curl -N 'https://sea.noc.andrii.net/api/1/ping' -d '{"target":"example.net","count":5}' # a UDP traceroute to 1.1.1.1 (one run: an address runs in its own family) curl -N 'https://sea.noc.andrii.net/api/1/trace' -d '{"target":"1.1.1.1","mode":"udp"}' # andrii.co's A and AAAA records from Cloudflare over DoH, reached over IPv4 (two runs, one per type) curl -N 'https://sea.noc.andrii.net/api/1/dns' -d '{"name":"andrii.co","type":"A, AAAA","server":"cloudflare","transport":"doh","families":["ipv4"]}' # andrii.co's TLS handshake and certificate chain on port 443, both families (two runs) curl -N 'https://sea.noc.andrii.net/api/1/tls' -d '{"target":"andrii.co","port":443}' ``` Your own connection, as the server sees it (the address, its AS and place, the TCP and TLS it negotiated): `curl 'https://noc.andrii.net/me'` for text, `curl 'https://noc.andrii.net/me?format=json'` for JSON. ## What it will and won't do - **Limits**, without signing in: 500 runs an hour and 3,000 a day per IPv4 address or IPv6 /64 (5× that per /24 or /48), one run in flight at a time. Each family and each DNS type is one run, and a family with no address isn't charged. Every `done` line carries what is left; a refusal for a limit says which (`rate_limited`, with `quota` and `retry_after_s`). - **Refused targets** (`target_refused`, HTTP 422, before anything is sent), each with a sentence saying what the address is and why: - "no address" or "this network" (RFC 791 §3.2; RFC 4291 §2.5.2) - a private address (RFC 1918) - carrier-grade NAT space (RFC 6598) - loopback (RFC 1122 §3.2.1.3; RFC 4291 §2.5.3) - link-local (RFC 3927; RFC 4291 §2.5.6) - reserved for a protocol's own use (ietf-protocol-assignments, RFC 6890 §2.1; ipv4-service-continuity, RFC 7335; ipv4-dummy-address, RFC 7600; nat64-dns64-discovery, RFC 8880, RFC 7050; nat64-local-use, RFC 8215; ietf-protocol-assignments, RFC 2928; srv6-sids, RFC 9602) - reserved for documentation and examples (RFC 5737; RFC 3849; RFC 9637) - the retired 6to4 relay anycast prefix (RFC 7526) - for lab benchmarking (RFC 2544; RFC 5180) - a multicast (or broadcast) address (IANA IPv4 Multicast Address Space; RFC 8190, RFC 919 §7; IANA IPv6 Multicast Address Space) - reserved, the old class E (RFC 1112 §4) - part of AS402801, the network this looking glass runs in - outside IPv6's global unicast space (2000::/3) - an IPv4 address inside an IPv6 one (an IPv4-mapped address, RFC 4291 §2.5.5.2; the NAT64 well-known prefix, RFC 6052; as a Teredo client's public address, RFC 4380 §4; 6to4, RFC 3056) - a discard prefix (RFC 6666) - in the retired ORCHID prefix (RFC 4843) - a unique local address (RFC 4193) An IPv6 address that carries an IPv4 one is refused and names the IPv4 address to measure instead. - **Malformed addresses** (`malformed_address`, HTTP 422): an input that can only be an IP address (it contains a `:`, or its last label is all digits) and isn't one is never looked up. It comes back with `malformed`: the `field`, the `family`, the problem's `code` and `message`, and the `spans` of what is wrong. `23.219.78.303` is refused as `ipv4_part_range`: "Not an IPv4 address: 303 is more than 255". - **Other refusals:** `bad_request` (HTTP 400: a parameter the server doesn't take, with the reason), `queue_full` (503), `internal` (500). ## Rules - Operational and diagnostic use only: checking a path, a name or a certificate, not scanning, and no load testing of third parties. - Each request to this site is logged with your IP address, the time, the page, the referring page and your browser, and each tool run with what was asked, for a year: to answer abuse reports and to see how the site is used. Your own report and the tools' results are not kept.
