Computers and Technology
1 answer:
Andrew [12]2 years ago
8 0

Answer:

False

Explanation:

IPv4 address are composed of four octets (8 bit numbers), ranging from <em>0.0.0.0 to 255.255.255.255</em>

All those 32 bits, in decimal notation, can form a total of

2^{32} = 4,294,967,296 different addresses.

Being more than 4 billion addresses and ignoring that some addressesare reserved for special uses, even present human population almost doubles that number.

So it is safe to state that IPv4 addresses is <u>not </u>enough to give every blade of grass its own IP.
