Function toPrefix

cli/command/network/connect.go:122–138

toPrefix converts n into a netip.Prefix. If n is not a valid IPv4 or IPV6 address, ToPrefix returns netip.Prefix{}, false. TODO(thaJeztah): create internal package similar to https://github.com/moby/moby/blob/0769fe708773892d6ac399ee137e71a777b35de7/daemon/internal/netiputil/netiputil.go#L21-L42
