jb51.net 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.

jb51.net 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.

Warnings

The character encoding “gb2312” is not widely supported. Better interoperability may be achieved by using “UTF-8”.

Using “gbk” instead of the declared encoding “gb2312”.

The “type” attribute is unnecessary for JavaScript resources.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.

Errors

Legacy encoding “gbk” used. Documents must use UTF-8.

The only allowed value for the “charset” attribute for the “meta” element is “utf-8”.

Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.

Bad value “mobile-agent” for attribute “http-equiv” on element “meta”.

Bad value “only screen and(max-width:640px)” for attribute “media” on element “link”: Expected a letter or whitespace but saw “(” instead.

Element “dl” is missing a required child element.

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

No “p” element in scope but a “p” end tag seen.

Bad value “true” for attribute “border” on element “img”: Only “0” is a permitted zero literal.

The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
