Tech & Internet Tools FAQ
Quick answers to the most common questions.
What does a subnet calculator show?
It typically shows network address, broadcast, usable host range, and the number of hosts for a given IP and CIDR/subnet mask.
What’s the best QR error correction level?
Use higher error correction when you expect damage/printing issues, and lower levels when you want smaller, simpler QR codes.
How accurate are time zone conversions?
They’re accurate as long as you pick the correct zones and dates (DST changes can shift results on specific days).
What is Screen PPD used for?
PPD (pixels per degree) helps compare perceived sharpness at a viewing distance—useful for monitors, VR, and display planning.
Can I use these tools for work?
Yes—these tools are built for quick checks and planning. For production decisions, always double-check requirements and standards.
