Port check is a free online tool to help you check whether the TCP port of a domain/IP Address is open.
You can check a single TCP Port, e.g. 80. Multiple ports, e.g. 22,80,443. Or range of ports, e.g. 1000-1100. For performance reason, one range can only contains maximum 100 TCP Ports
Single port check does not require recaptcha. Otherwise, it is required.

The Ping utility is an online free tool that help you to verify if a domain/server is operating and network accessible.
Ping uses the ICMP protocol’s mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams (“pings”) have an IP and ICMP header, followed by a struct timeval and then an arbitrary number of “pad” bytes used to fill out the packet.

The Traceroute utility is an online free tool that help you to track the route packets taken from this server on their way to a given host. It utilizes the IP protocol’s time to live (TTL) field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to the host.
