Which of the following IPv4 addresses can be directly used by a host to access the Internet?
Which of the following IPv4 addresses can be directly used by a host to access the Internet?
In IPv4, certain address ranges are designated for private networks and cannot be used directly to access the Internet. These ranges are: 10.0.0.0 to 10.255.255.255 (Class A), 172.16.0.0 to 172.31.255.255 (Class B), and 192.168.0.0 to 192.168.255.255 (Class C). Given these ranges, options A (192.168.1.1/24), B (10.255.255.254/24), and C (172.16.255.254/24) are all within the private IP address ranges. Option D (172.32.1.1/24) does not fall within these private IP address ranges and can therefore be used directly by a host to access the Internet.
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
La que no es privada
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 answer is D. 172.32.1.1 For private addres is : 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255
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.

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.
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.
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
The answer is D
