Onion Domain Name Resolution
A legacy client may inadvertently attempt to resolve a onion name through the DNS. This is just another way ENS is supporting things beyond the Ethereum ecosystem.

How do you resolve a domain while using Tor.
Onion domain name resolution. RFC 7686 classifies the onion TLD as a special-use domain but I dont see anything in those RFCs that requires an operating system to avoid name resolution for them. Domain name resolution is a Tor attack vector but dont worry. V3 onion domains are SHA3 based.
This protocol helps services make their existences known and helps clients find services while preserving the anonymity and the location IP address of both client and service. Cockmailwwfvrtqjonion Server iP Current resolution website server lookup history. Web searches have frustratingly produced very little of value.
At the time of writing two top-level domain names reserved by inclusion in the Registry are used by name resolution protocols other than the DNS and went through the process. If I attempt to resolve somethingonion then theres radio silence. These names can only be resolved by a Tor client because of the use of onion routing to protect the anonymity of users.
RFC 7686 reserves the use ofonion for the self-authenticating names of Tor hidden services. Local is used by the Multicast DNS protocol specified in which is similar in some respects to the DNS but which uses a different well-known port number and is limited to a particular multicast scope. Dark Web visitors do not use the public DNS to resolve onion names to Internet Protocol IP addresses instead resolution occurs using the entirely separate Tor hidden service protocol.
Dont Panic in large friendly letters on the cover. Caching servers where not explicitly adapted to interoperate with Tor SHOULD NOT attempt to look up records for onion names. As you correctly deduced you cannot resolveonion domains via the normal DNS system because this is a reserved top-level domain specifically for use by Tor and such domains by design have no IP addresses to map to.
The process of returning an IP address given a domain name is called DNS resolution. It looks up their introduction point on the hidden service directories - see Is it possible to look up the public key for a onion-address. These semantics are open to revision later as the Tor community evolves its canonical naming semantics.
Since Tor still uses IP addresses you still need to do DNS resolution to browse the web over Tor. Name Resolution APIs and Libraries MUST either respond to requests for onion names by resolving them according to tor-rendezvous or by responding with NXDOMAIN. Then a rendezvous point is set up where the hidden service and the client meet - answers to How do onion addresses exactly work.
ONION is used to construct names that designate services reachable via the Tor network using onion routing. Resolvers MUST either respond to requests for onion names by resolving them according to tor-rendezvous or by responding with NXDOMAIN. Bit means that a domain name will resolve to any of onion IPv6 IPv4 or CNAME meaning that bit names are only encrypted and authenticated if TLS is used.
Resolvers MUST either respond to requests for onion names by resolving them according to tor-rendezvous or by responding with NXDOMAIN. Semantically bitonion means that a domain name will always resolve to a onion address meaning that bitonion names are encrypted and authenticated regardless of whether TLS is used. Tor soups up onion sites with bountiful browser bump.

This causes a disclosure that the client is attempting to use Tor to reach a specific service. Onion services are Tor nodes that advertise their public key encoded as an address with onion TLD and establish connections entirely within the Tor network. This use case is distinct from the use case for Special-Use Domain Names like local and onion in that the names are resolved using the DNS protocol but they do require extensions or exceptions to the usual DNS resolution to enforce resolution in a local context rather than the global DNS context.
The onion routing technique that Tor uses to achieve a high level of anonymity gave rise to the onion name. They are 56 characters long. It doesnt resolve them in the common sense - there is no DNS involved at all.
As previously announced the Ethereum Name Service ENS now supports the resolution of Tor onion addresses. Privacy researchers have worked out that Tors use of the domain name system DNS can be exploited to identify users. RFC 6762 reserves the use oflocal for link-local host names that can be resolved via the Multicast DNS name resolution protocol.
Name Resolution APIs and Libraries. On 9 September 2015 ICANN IANA and the IETF designated onion as a special use domain giving the domain an official status following a proposal from Jacob Appelbaum of the Tor Project and Facebook security engineer Alec Muffett.
