Minimal website to look up the Ethereum hexadecimal (0x) address for every ENS (.eth) name in a list.
The keccak256 implementation is from Paul Miller's noble-hashes library.

This tool will report an address of 0x0000000000000000000000000000000000000000 for ENS names that do not have an address set, or that use a custom ENS resolver.
The official method of resolving an ENS name requires (1) getting the ENS resolver for the name, then (2) asking the resolver for the name's address.
To complete the lookup in one network request, this tool skips step (1) above and instead directly queries all the names against the ENS resolvers "ENS: Public Resolver 2" (0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41) and "ENS: Old Public Resolver 2" (0x226159d592E2b063810a10Ebf6dcbADA94Ed68b8). These two resolvers will handle the majority of ENS names, but this tool will miss ENS names where the owner has set a custom resolver.
