How Looking Glass Service Works

Looking Glass provides the capability to perform fundamental checks and diagnostics on the server.net network's status and to extract information from the routing table. This tool is intended primarily for users who have a basic grasp of Internet operations.

With Looking Glass, you can remotely inspect various server.net network metrics, including route, response time, and traceroute to a specific host. This tool also allows you to view internet address access parameters using the following utilities:

Ping Command

Examine the accessibility and delay of Round Trip Delay (RTD) data packets from the server.net network to a particular Internet resource. The Ping command is used to assess both the availability and the quality of communication with a specified Internet resource. It provides a list of responses (ICMP Echo-Reply). Additionally, by measuring the time taken from sending a request to receiving a response, you can determine the round-trip delays (RTT) along the route and identify packet loss frequency, which helps in assessing the load on data transmission channels and intermediate devices.

Traceroute Command

Identify the routers that facilitate access from the server.net network to a given Internet resource, and measure the Round Trip Delay (RTD) of data packets to each of these routers. The Traceroute command helps trace the route that packets take through the IP network from point A to point B. The output of the Traceroute command will be a list of all intermediate nodes between A and B, along with the delay time to each node; this includes the time required for a packet to travel to the node and return.

MTR Command

My Traceroute (MTR) combines the features of both 'traceroute' and 'ping' into a single network diagnostic utility. Upon starting, MTR examines the network path between the host where it is running and a user-defined destination. It identifies each network hop between the two endpoints and sends a series of ICMP ECHO requests to each hop to evaluate the quality of the connection to each node. Throughout this process, MTR provides ongoing statistics about each node in the path.

Server.net Looking Glass Service supports both IPv4 and IPv6 addresses.
