When trying to add a destination UserNetwork, the message "The address is incorrect" is displayed.

The four addresses below cannot be registered as a destination UserNetwork and therefore the message "The address is incorrect" is displayed.
-0.0.0.0/0
-10.0.0.0/8
-172.16.0.0/12
-192.168.0.0/16

Note that this error also occurs and the address cannot be registered when (1) the host address is set to other than "/32," (2) there is an incorrect relation between the network address and subnet, (3) a global IP address is entered, and (4) wrong IP address is entered (like, extra "0" is included).

[Examples]
 (1)192.168.0.1/24 (correct address: 192.168.0.1/32)
 (2)192.168.1.64/24 (correct address: 192.168.1.64/26)
 (3)200.200.200.1/32 (global IP addresses cannot be registered)
 (4)192.168.00.1/32 (correct address: 192.168.0.1/32)

If you would like to use the address range mentioned above, please divide the segment in two, and make two destination addresses.

[Examples]
* When you would like to use 10.0.0.0/8(10.0.0.1 ~ 10.255.255.254)
 > 10.0.0.0/9 and 10.128.0.0/9

* When you would like to use 172.16.0.0/12(172.16.0.1 ~ 172.31.255.254)
 > 172.16.0.0/13 and 172.24.0.0/13

* When you would like to use 192.168.0.0/16(192.168.0.1 ~ 192.168.255.254)
 > 192.168.0.0/17 and 192.168.128.0/17
