Online IP Network Tools
This is a set of IP network tools for use in troubleshooting and testing. These are various
standard tools that have been scripted to allow execution and output from this site.
Some of these tools may take a moment to execute before their output is shown.
PING
Ping is a utility used to test the reachability of a host on an IP network and to measure
the round-trip time for messages sent from the originating host to a destination computer and back.
used to test the reachability of a host on an Internet Protocol (IP) network and to measure the
round-trip time for messages sent from the originating host to a destination computer and back.
TRACEROUTE
Traceroute is a diagnostic tool for displaying the route (path) and measuring transit
delays of packets across an IP network. The history of the route is recorded as the
round-trip times of the packets received from each successive host in the route;
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.
WHOIS
WHOIS is a query and response protocol that is widely used for querying databases that store
the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or
an autonomous system, but is also used for a wider range of other information. The protocol stores and
delivers database content in a human-readable format.
MXLOOKUP
A mail exchanger record (MX record) is a type of resource record in the Domain Name System
that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain,
and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX
records of a domain name specify how email should be routed with the Simple Mail Transfer Protocol (SMTP).
NSLOOKUP
nslookup is a network administration command-line tool for querying the Domain Name System
(DNS) to obtain domain name or IP address mapping or for any other specific DNS record.
MTR
MTR is a dynamic alternative to the traceroute program. Combining the functionality of ping and
traceroute, mtr allows you to poll a remote server and see how the latency and performance changes over time.
This tool will return the MTR output in report form (10 cycles) and will not execute continually.
DNSProp
DNS propagation check. New or changed DNS records can take up to 24 hours to propagate throughout the world. This tool
Performs a convenient way to lookup any domain name record across multiple DNS servers throughout the world to
confirm whether or not a changes has been fully propagated. This is also nice for checking geographical source-based DNS.
Nmap
Nmap (Network Mapper) allows you to discover which TCP ports are open on a target host and report back those that are open,
and what service is running on them. Network ports are the entry points to a machine that is connected to the Internet.
A service that listens on a port is able to receive data from a client application, process it and send a response back.
Malicious clients can sometimes exploit vulnerabilities in the server code so they gain access to sensitive data or execute
malicious code on the machine remotely.
