IP range: 126.63.0.0 - 126.63.255.255 (126.63.0.0/16) , IPv4
Geographic Region: Asia
This range is also known as "Class B" and it contains 65,536 (65k) IP addresses with the first address starting at 126.63.0.0 and the last address of this range ends at 126.63.255.255.
When using the CIDR range (Classes Inter Domain Routing) classification it is also typical
to call this range 126.63.0.0/16. Since IPv4 addresses are represented using 32 bits, this way of writing describes the range as all the addresses where the first 16 bits are
preserved from the address 126.63.0.0. That means that there are 16 bits which are constant, and 16 bits that are changing. Hence, 65k addresses.
This is an inner range inside the parent range 126.0.0.0/8 that belongs to APNIC. Inner ranges are associated seperately to different private organizations, so if you're interested
in finding out which organization controls this specific range, you can browse deeper into the IP addresses themselves where we have a WHOIS tool that can reveal this information.
