to a multicast address and another one linked to a unicast address.
*Fast DDS* allows for the configuration of an initial peers list which contains one or more such IP-port address
pairs corresponding to remote DomainParticipants PDP discovery listening resources, so that the local
DomainParticipant will not only send its PDP traffic to the default multicast address-port specified by its domain,
but also to all the IP-port address pairs specified in the initial peers list.
DomainParticipant will only send its PDP traffic to the IP-port address pairs specified in the initial peers list.

A DomainParticipant's initial peers list contains the list of IP-port address pairs of all other DomainParticipants
with which it will communicate.
It is a list of addresses that a DomainParticipant will use in the unicast discovery mechanism, together or as an
alternative to multicast discovery.
It is a list of addresses that a DomainParticipant will use in the PDP discovery mechanism, and can hold both multicast
and unicast addresses.
The default multicast address will be used if the list is empty.
Therefore, this approach also applies to those scenarios in which multicast functionality is not available.

According to the `RTPS standard <https://www.omg.org/spec/DDSI-RTPS/2.2/PDF>`_ (Section 9.6.1.1), the RTPSParticipants'
