You can use Disk Management to change the drive letter to R:

Ipv4 addresses

are 32 bits long and consist of 4 octets, which is a group of 8 bits each, separated by a period. They are normally presented in dotted decimal notation, meaning each group of 8 bits is shown as a decimal number less than 256, with a period between each number, such as 192.168.1.1.

IPv6 addresses

are a 128-bit IP address presented as eight segments of four hexadecimal numbers each, separated by a colon. Where the hexadecimal number is 0 in any segment, it can be omitted and replaced simply by double colons (::). If consecutive segments are 0, they can be replaced by a single set of double colons, but only one set of double colons can exist in any given address-otherwise, you wouldnt be able to tell how many sets of zero are in each part of the IP address. *ex: fe80::308c:fee2:dabc:8337, the expanded address would be fe80:0:0:0:308c:fee2:dabc:8337. The first 3 segments (48 bits) are the site prefix, and the 4th segment (64 bits) are the interface ID, also sometimes called a token.

Addresses in the 192.168.x.x range
