A host performs Duplicate Address Detection (DAD) before actually activating the given address on the interface

RFC 2462 has to say about this:

5.4. Duplicate Address Detection

Duplicate Address Detection is performed on unicast addresses prior
to assigning them to an interface whose DupAddrDetectTransmits

variable is greater than zero. Duplicate Address Detection MUST take

place on all unicast addresses, regardless of whether they are

obtained through stateful, stateless or manual configuration, with

the exception of the following cases: [...]

The original RFC was updated/modernized by RFC 4429 and further on by RFC 7527

EDIT
To nitpick a bit: the correct sequence of RFCs is more precisely:

RFC 1971, obsoleted by RFC 2462, obsoleted by RFC 4862, updated by RFC 7527
