What is a ping?

Ping Test is a computer network administration program used to test whether a particular host is reachable across an Internet Protocol (IP) network and to measure the round-trip time for packets sent from the local host to a destination computer, including the local host's own interfaces.

  • What is a Ping Assist Pro?

    Ping Assist Pro is a windows ping test program. This windows ping tool verifies a connection to a remote host by sending an ICMP (Internet Control Message Protocol) ECHO packet to the host and listening for an ECHO REPLY packet. A message is always sent to an IP address. If you do not specify an address but a hostname, this hostname is resolved to an IP address using your default DNS server. In this case you're vulnerable to a possible invalid entry on your DNS (Domain Name Server) server. Ours windows ping program can notify you when abnormal situations arise in several ways, for example, this windows ping test program can show a message in the system tray, play a sound file, or send a text message by email. In addition, this windows ping tool can send e-mail status messages at a specified time, containing information about abnormal situations that have occurred.

  • TTL (Time To Live)

A field in the Internet Protocol (IP) that specifies how many more hops a packet can travel before being discarded or returned.

  • ICMP (Internet Control Message Protocol)

  • An extension to the Internet Protocol (IP) defined by RFC 792. ICMP supports packets containing error, control, and informational messages. The Ping and Trace utilities, for example, uses ICMP to test an Internet connection.

  • Echo reply

The echo reply is an ICMP message generated in response to an echo request, and is mandatory for all hosts and routers.

  • TCP (Transmission Control Protocol)

Is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

  • Default

This is the fallback value. If nothing else is specified the default value will be used. If you install ours windows ping software, it generally installs with the default settings, and you can customize it afterwards with your preferences.
