Why primary vs forward-resolving names is a security boundary

Forward versus primary names visual

ENS supports two ways of associating names with addresses.

  1. A name can forward resolve to an address (myname.eth -> 0x1234…).
  2. An address can declare a primary name which contains a forward resolving address record and a reverse record that points back to the name (0x1234… -> myname.eth).

It’s important to be aware of this distinction between forward resolution and primary names as it defines a security boundary within ENS.
