The app checks user hosts against multiple DNS blacklists, presenting the information simply. It determines which RBLs list hosts from the user's monitoring list using ultrafast asynchronous network I/O.
Ping allows users to ping devices by IP or domain. IPv4 info retrieves location, ISP, ASN, and announcements for public IPs. prefix info displays IP prefixes and ISP correlations. ASN info provides details about autonomous systems.
Calculate sizes and compare rim compatibility. Input measurements to determine proper fit. Display results in a today widget for quick reference. Track step-by-step calculations for accuracy.
Calculate estimated using vehicle weight, elapsed time, and quarter-mile speed. Input driver, passenger, and load weights. Results are estimations based on ET or trap-speed methods. Export calculations for reference.
Calculate designs according to ASTM E 1300 standards. Choose support sides, glazing angles, and up to three lites. Customize heat treatment, thickness, and lamination for each lite. Enter dimensions and load values in SI or US units.
Calculate for steel, aluminum, copper, brass, stainless steel, and more. Input dimensions and material type to estimate . Supports multiple shapes including sheets, bars, and pipes. Save and export calculation results.
Connect to and private virtual private network (VPN) servers in 30+ countries. Hide IP address, encrypt internet traffic, and protect public Wi-Fi connections. Choose from high-speed servers for stable performance.
Convert currencies and cryptocurrencies using real-time exchange rates. Support for global currencies and popular digital assets. Calculate interest and repayment amounts for reference.
Calculate to determine maximum circuit distance and minimum conductor size. Input parameters to find required conductor size, actual loss, maximum allowable loss, and maximum amps. Use NEC® table T310.15 (B) (16) 75°C ratings for amperage values.
The app allows users to record news, promos, segues, or bits and send them to NexGen Digital via WANcasting or FTP. This feature enables direct loading into the automation system, saving time at the station.
Calculate costs based on miles per gallon or liters per 100km. Determine cost per mile or kilometer. Compare fuel cost differences between vehicles. Estimate duration. Convert units between miles and kilometers.
