224.0.0.1 is an IPv4 multicast address

224.0.0.1 is in the IPv4 multicast range 224.0.0.0/4. A multicast address represents a group of receivers, not one individual computer or public endpoint.

Multicast is used for one-to-many delivery on networks. The mapped representation ::ffff:e000:1 can be useful when reading dual-stack software output, but it does not convert an IPv4 multicast group into an IPv6 multicast group.

In particular, 224.0.0.1 is the all-hosts multicast group on the local subnet, not the address of one server. Treat a mapped multicast value as a group identifier when interpreting a capture or log.

IPv4 multicast space is registered by IANA.
