No, it doesn't have to be an IPv4 address. There is nothing that I know of in MPIR that excludes IPv6. The "host_name" field of the procdesc structure is a string pointer, so the string can resolve to an IPv4 or IPv6 address. And as it says in the document, on BProc systems, "host_name" is a BProc node number so the string is also open to interpretations other than just IP address.
