priority - 17 Size tap targets appropriately

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

The tap target <a href="/privacy.html" class="cc_more_info">See details</a> is close to 2 other tap targets.

The tap target <a href="http://www.cut…ithmetic.shtml">Arithmetic</a> and 9 others are close to other tap targets.

The tap target <a href="http://www.cut…nversion.shtml">Base Conversion</a> and 305 others are close to other tap targets.

priority - 3 Configure the viewport

Your page specifies a fixed-width mobile viewport. Consider using a responsive viewport to allow your page to render properly on all devices.

Configuring a viewport specifying width=device-width instead of width=320 will allow your page to adapt for devices of various widths. This may require additional work if the styling on your page relies on a fixed-width layout.

cut-the-knot.org Ping

Ping is a networking utility tool to test if a particular host is reachable. It is a diagnostic that checks reachability of a host on an Internet Protocol (IP) network. In a computer network, a ping test is a way of sending messages from one host to another. Aside from checking if the host is connected to a network, ping also gives indicators of the reliability and general speed of the connection.


cut-the-knot.org TRACEROUTE

Traceroute is a network diagnostic tool used to track the pathway taken by a packet on an IP network from source to destination. Traceroute also records the time taken for each hop the packet makes during its route to the destination. Traceroute uses ICMP (Internet Control Message Protocol) echo packets with variable time to live values. The response time of each hop is calculated. To guarantee accuracy, each hop is queried multiple times (usually three times) to better measure the response of that particular hop.
