Rede máscara calclulator

Rede máscara calculadora é un servizo de rede usado para calcular rede máscara por subred gama. Unha máscara de subrede é un mecanismo usado para dividir unha rede en subnetworks; pode ser usado para reducir o tráfico en cada subnetwork por limitar o tráfico para só o subnetwork(s) para o que se destina, así, eliminando problemas de asociados conxestión nas outras subnetwork(s) and reducing congestion in the network as a whole. Each subnet functions as though it were independent, keeping traffic local and forwarding traffic to another subnetwork only if the address of the data is external to the subnetwork.

Subnetting an IP network allows for the flow of network traffic to be segregated based on a network configuration. It essentially organizes the hosts into logical groups, and provides for improving network security and performance. The most common reason for subnetting IP networks is to control network traffic.

Traditionally, in an Ethernet network, it is very common for all nodes on a segment to see all the packets transmitted by all the other nodes on that segment, which introduces collisions, and the resulting retransmissions under heavy traffic loads. For additional information on subnetting, see RFC 1817, and RFC 1812.

Calculator calculate the subnet mask to use, given a TCP/IP network address and the number of subnets or nodes per subnet required. To create the subnet mask, first remember that the purpose of the subnet mask is to separate the (32 bit) ip address into the network prefix and the host number. If a bit in the subnet mask is 1, the corresponding bit in the IP address is part of the network address; se a pouco a máscara de subrede é 0, o correspondente pouco no enderezo IP é a parte do enderezo de servidor.
