Question

Can someone help me with this question?

How big is the MAC address space? The IPv4 and IPv6 address space?

Thanks

Answer 1

A MAC has 6 tuples of hexidecimal values (12 places for values).

IPv4 uses 32-bit addressing.

IPv6 uses 128-bit addressing.



Therefore:

MAC : 16^12 = 281474976710656 addresses

IPv4 : 2^32 = 4294967296 addresses

IPv6 : 2^128 = 3.4028236692093846346337460743177e+38 addresses.

they are in many circumstances allotted to an ISP in blocks/chunks. So the ISP will decide for a fashion they like to supervisor their block of IP addresses to generate the main money. some will use a dynamic scheme wherein whenever a consumer connects to their community, they are issued with a sparkling IP address (if the hire time is up on the single before allotted to them) or the ISP would desire to apply a static scheme wherein they have an IP address for each physique of their purchasers. different ISPs which comprise AOL use a various scheme the place they run their very own inner community and the customer gets an IP address which could't be unique on the internet, yet is unique on the AOL community. ISPs in different worldwide places now and back use a scheme the place they are going to allocate an IP address to each development or each floor of a development the place an information superhighway connection technique exists and then the purchasers are area of an community section community and their get right of entry to to the internet is by a NAT router it is the two placed at each floor or each development. Ukraine is an occasion of a u . s . a . working considered one of those scheme. in this scheme a single IP address would desire to represent hundreds of folk. additionally do no longer forget information superhighway cafes, they might have diverse setups concerning to information superhighway IP addresses and how they are utilized of their corporation. back hundreds of folk would desire to have gained information superhighway get right of entry to by a single IP address in 24 hours in an information superhighway cafe.

Answer 3

MAC addresses in IPv4 are composed of twelve hexadecimal digits. Each hexadecimal digit can take on one of sixteen values, so its address space is composed of 16^12 values with the range 0000.0000.0000 to FFFF.FFFF.FFFF.

(16^12 = 281,474,976,710,656.)



MAC addresses in IPv6 are composed of twenty-four hexadecimal digits; thus, its address space is composed of 16^24 values with the range 000:0000:0000:0000:0000:0000 - FFFF:FFFF:FFFF:FFFF:FFFF:FFFF.

(16^24 = 79,228,162,514,264,337,593,543,950,336. That's seventy-nine octillion, two hundred twenty-eight septillion, one hundred sixty-two sextillion, five hundred fourteen quintillion, two hundred sixty-four quadrillion, three hundred thirty-seven trillion, five hundred ninety-three billion, five hundred forty-three million, nine hundred fifty thousand, three hundred thirty-six.)
