## What is TTL Calc & Ping?

TTL Calc & Ping brings two everyday network tools together: a DNS TTL converter and a ping tool. Switch between them with the TTL | Ping toggle at the top of every screen.

Planning a DNS migration, moving a website to a new server or tuning your zone file? You know you want "a day" or "five minutes", but the record needs 86400 or 300. The converter does it instantly, so you never have to multiply by 3600 in your head again.

TIME TO TTL
Enter hours and minutes and get the TTL in seconds, ready to paste into your DNS panel.

TTL TO TIME
Found a TTL of 14400 in a zone file? See at a glance that it means 4 hours.

PING
Enter a domain or an IP address (a pasted URL works too) and watch the replies arrive live, with round-trip times. Stop after 5, 10, 20, 50 or 100 packets, or keep going until you tap Stop. Choose IPv4, IPv6 or Auto, which follows your device's preference.

PING STATISTICS
Sent, received and lost packets, packet loss in percent, plus min, average, max and standard deviation of the round-trip time.

HISTORY
Your last 50 conversions and pings are kept on your device. Tap any of them to load it back, delete single entries, or clear the list. For pings, only the host and the settings are saved.

ONE-TAP COPY
Copy any result to the clipboard and paste it straight into your DNS provider's control panel.

LEARN THE BASICS
A short guide explains what TTL is, and when a short or long value makes sense.

BUILT FOR IPHONE AND IPAD
Clean, modern design with light and dark mode, in English and Hungarian.

PRIVATE BY DESIGN
No account, no ads, no tracking. The TTL converter works fully offline. The network is used only when you start a ping, and then only to reach the host you entered. Nothing is ever sent to the developer.
