What is a namehash?
The EIP-137 algorithm that turns a name into the 32-byte node ENS contracts use as a key: hash each label with keccak-256 and fold them right to left. It runs locally on this page; only the resolution step touches an RPC.
Why is reverse resolution "verified"?
Anyone can point a reverse record at any name, so a reverse result is only trustworthy if the name also resolves forward to the same address. This tool performs that round-trip and marks the result verified only when both directions agree.
Why does my exotic name give a different result elsewhere?
Full ENS normalization (ENSIP-15) handles emoji, confusable characters, and special casing rules. This tool applies basic lowercasing, which matches standard ASCII names; heavily stylized names may normalize differently in wallet software.
Which records does this read?
The ETH address record (addr) and the primary name record. ENS also stores avatars, content hashes, and text records; those are out of scope here and readable on the official ENS app.
