The address signature can be verified as follows:

func TestVerifyAddress(t *testing.T) {
	pub := "d7e63ddca1e41d311db9668bb0f6ff549cab9c24de03ecaa1643940a8fdc3937"
	address := "1.1.1.1"
	addressSignature := "0xa200e73f5f5a34ddefbf23349fea3fcee6c39f42404a37360339f69d18b71b59e08c34277b9638a5642683c5896d22ac0c6cc89d4734f712422eb5edcff6270c"
	P, _ := hex.DecodeString(pub)
	M := []byte(address)
	S, _ := hexutil.Decode(addressSignature)
	if !Verify(P, M, S) {
		t.Fatal("verify failed")
	}
	if err := VerifySig(P, M, S); err != nil {
		t.Fatal("verify sig failed")
	}
