## Fallback contract support
In order to better support content resolution on different service providers (such as Swarm and IPFS), [EIP-1577](https://eips.ethereum.org/EIPS/eip-1577)
was introduced and with it changes that allow applications to know _where_ content hashes are stored (i.e. if the
requested hash resides on Swarm or IPFS).
The code under `contracts/ens/contract` reflects the new Public Resolver changes and the code under `fallback_contract` allows
us to support the old contract resolution in cases where the ENS name owner did not update her Resolver contract, until the migration
period ends (date arbitrarily set to June 1st, 2019).
