this 12 IPs can be one network 
example
210.130.10.12/28
Address:   210.130.10.12         11010010.10000010.00001010.0000 1100
Netmask:   255.255.255.240 = 28  11111111.11111111.11111111.1111 0000
Wildcard:  0.0.0.15              00000000.00000000.00000000.0000 1111
=>
Network:   210.130.10.0/28       11010010.10000010.00001010.0000 0000
(Class C)
Broadcast: 210.130.10.15         11010010.10000010.00001010.0000 1111
HostMin:   210.130.10.1          11010010.10000010.00001010.0000 0001
HostMax:   210.130.10.14         11010010.10000010.00001010.0000 1110
Hosts/Net: 14

or it could be 12 IP's link
210.130.10.17-19
210.130.10.35-39 ...
