Private IP addresses are used to relieve the problem of IP address shortage. They are used on internal networks and hosts and cannot be used on the public network.
Private IP Addresses include a range of Class A, B and C addresses.
Class A: 10.0.0.0 - 10.255.255.255
Class B: 172.16.0.0 - 172.31.255.255
Class C: 192.168.0.0 to 192.168.255.255
Option D (172.32.1.1) is the only one which falls out of the range of private IP addresses
Answer is D.
A. 192.168.1.1/24 - It is a private IP address class C. Can´t directly access the internet.
B. 10.255.255.254/24 - It is a private IP address class A. Can´t directly access the internet.
C. 172.16.255.254/24 - It is a private IP address class B. Can´t directly access the internet.
D. 172.32.1.1/24 - It is not a private IP adrress. It can directly access the internet.
B
Out of the given options, only option B (10.255.255.254/24) can be directly used by a host to access the Internet. This is because it falls within the range of private IP addresses (10.0.0.0 - 10.255.255.255), which are reserved for internal use within private networks. The other options (A, C, and D) also fall within the range of private IP addresses and cannot be directly used to access the Internet.
B. 10.255.255.254/24
Among the options provided:
192.168.1.1/24: This is a private IPv4 address from the range reserved for private networks and cannot be directly used on the Internet.
10.255.255.254/24: This is also a private IPv4 address from the range reserved for private networks. While it's a private address, the option presented here is technically a valid private address.
172.16.255.254/24: Like the previous options, this is a private IPv4 address from the reserved range for private networks.
172.32.1.1/24: This is not a valid private or public IPv4 address. The valid range for the second octet in the private address space is 16-31.
Dos endereços IPv4 listados, apenas o endereço C, 172.16.255.254/24, pode ser usado diretamente por um host para acessar a Internet.
Os endereços IPv4 que começam com 10.x.x.x, 172.16.x.x - 172.31.x.x e 192.168.x.x são endereços privados que são usados em redes locais (LANs) e não são roteáveis pela Internet pública.
the correct answer is D. 172.32.1.1/24. This is the only IPv4 address that is not in the private address range and can be directly used by a host to access the Internet
