 Your browser may have a local cache of the content in question and might not reflect that something has been blocked on the gateways.

+### Supported Features
+
+The above public gateways support the following:
+
+- `ipfs.io` and `dweb.link` support the [full set of IPFS Gateway specifications](https://specs.ipfs.tech/http-gateways/).
+- `trustless-gateway.link` supports only the [Trustless Gateway subset of the specification](https://specs.ipfs.tech/http-gateways/trustless-gateway/).
+
+They support HTTP clients reaching them over both ipv4 and ipv6 addresses
+
+The underlying IPFS nodes backing the gateways support the following mutable identifiers under the `/ipns` namespace:
+- IPNS Public Keys, e.g. `dweb.link/ipns/k51q....`
+- DNSLink for all [ICANN](https://en.wikipedia.org/wiki/ICANN) registered domains as well as `.crypto` and `.eth`, e.g. `dweb.link/ipns/vitalik.eth`
+
+The underlying IPFS nodes backing the gateways support retrieving data from peers that:
+- Have either ipv4 or ipv6 addresses
+- Are either reachable over the public internet or are accessible via libp2p's relay-v2 protocol and reach out to the gateway nodes via dialback
+- Support one of the following libp2p transport configurations:
+   - QUIC-v1
+   - TCP or WS or WSS, Yamux, TLS or Noise
+   - WebTransport
+- Support the [Bitswap](./bitswap.md) protocol ([v1.2](https://specs.ipfs.tech/bitswap-protocol/#bitswap-1-2-0), [v1.1](https://specs.ipfs.tech/bitswap-protocol/#bitswap-1-1-0) or [v1.0](https://specs.ipfs.tech/bitswap-protocol/#bitswap-1-0-0))
+- Have either advertised their data to the Amino DHT, or have advertised to IPNI such that their data has been indexed by [cid.contact](https://cid.contact)
