princetoninstruments.com Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.

princetoninstruments.com TRACEROUTE

Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.

Errors

Obsolete doctype. Expected “<!DOCTYPE html>”.

Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).

Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.

Duplicate attribute “rel”.

Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)

Element “div” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)

Stray doctype.

Stray start tag “html”.

Stray start tag “head”.

Attribute “http-equiv” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.

Element “title” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

Stray end tag “head”.

Start tag “body” seen but an element of the same type was already open.
