Frequently asked questions about IT calculators
What IT calculators are available on Calc1.ru?
Calc1.ru offers calculators for: IP addresses and subnets (IPv4/IPv6, CIDR), hashrate for mining cryptocurrencies (Bitcoin, Ethereum and others). All calculators work online and are absolutely free.
How accurate are IT calculators?
The calculators use the latest network addressing standards (RFC) and mining formulas used in blockchain networks. Accuracy depends on the correctness of the entered data. For professional use, calculators provide highly accurate results.
Are IT calculators free to use?
Yes, all IT calculators on Calc1.ru are completely free. You can use them an unlimited number of times without registration or hidden fees.
How to calculate subnet parameters by IP and CIDR?
Use an IP address calculator by entering an IP address with CIDR notation (for example, 192.168.1.0/24). The calculator will show the network address, IP range, subnet mask, number of hosts and other parameters.
How to calculate the profitability of cryptocurrency mining?
Use the hashrate calculator by entering hardware hashrate, network difficulty, block reward, block time, energy consumption and electricity cost. The calculator will calculate profitability, profit and payback.
How to calculate the number of hosts in a subnet?
In the IP address calculator, enter CIDR notation or IP with mask. The calculator will automatically calculate the number of available hosts using the formula: 2^(32-CIDR) - 2 for IPv4.
How to calculate the payback of mining equipment?
In the hashrate calculator, enter the cost of the equipment and calculate the net profit. Payback = Cost of equipment / Net profit per day. The result will show the number of days until payback.
Does the calculator support IPv6 addresses?
Yes, the IP address calculator fully supports both IPv4 and IPv6 addresses. You can calculate subnets for both versions of the IP protocol.
How to take into account the mining pool commission when calculating?
In the hashrate calculator, enter the percentage of the pool commission (usually 1-3%). The calculator will automatically subtract commission from income when calculating net profit.
How to calculate the broadcast address of a subnet?
Use an IP address calculator. The broadcast address is calculated automatically as the last address in the subnet range and appears in the results.
