Network Tools
These tools allow you to query and perform operations on networks and IP addresses.
AS Network WHOIS Lookup
AS (autonomous systems) are individual networks that, together, make up the global Internet as we know it.
About the AS Network WHOIS Lookup tool
Network packets (traffic) are transmitted over the Internet by traversing multiple networks run by different organisations - known as Autonomous Networks. Each of these organisations is assigned a number for their network, known as an ASN (Autonomous System Number.)
Each network peers with other networks, sharing the AS numbers of the networks they peer with.
You can perform a query known as "WHOIS" to identify which organisation operates a particular AS network.
Use Cases
Use the AS Network WHOIS tool on Solid Tools for Developers to:
- Identify which organisation is responsible for an ASN
- Find out contacts to report abuse or technical problems with an ASN
Usage
Enter an ASN in the "AS Number" field.
Optionally select a regional WHOIS server to send your query to.
Results
The raw output from the WHOIS database will be displayed.
The following example shows a WHOIS lookup for AS15418, the AS number allocated to Fasthosts - the company and data centre that hosts the server running Solid Tools for Developers.

IP Whois
"Whois" is a tool on Unix and Linux servers that queries WHOIS servers for ownership of domains, IP addresses and networks.
About the IP WHOIS Lookup tool
All computers or servers on the Internet have an IP address. IP addresses are allocated to organisations in blocks of contiguous addresses, who then allocate ranges within their allocation to their customers.
You can perform a query known as "WHOIS" to identify which organisation an IP address is allocated to.
Use Cases
Use the IP WHOIS tool on Solid Tools for Developers to:
- Identify which organisation is responsible for an IP address
- Find out contacts to report abuse or technical problems with an IP address
Usage
Enter an IPv4 or IPv6 address in the "IP address" field.
Optionally select a regional WHOIS server to send your query to.
Results
The raw output from the WHOIS database will be displayed.
The following example shows a WHOIS lookup for 2a00:da00:1800:15a::6 - the IPv6 address of the Solid Tools for Developers web application.

Ping
Ping is a mechanism for checking if a host (IP address) is alive and responding.
About the Ping tool
All computers or servers on the Internet have an IP address. "Pinging" this IP address is the quickest way to check if you can reach a particular computer, server or router.
If you are unable to ping an IP address, it may mean the computer or server is turned off, or another network problem is preventing you from accessing it.
Use Cases
Use the Ping tool on Solid Tools for Developers to:
- See if an IP address can be reached from the Internet
- Check if your local firewall is blocking ping requests (ICMP traffic)
- Eliminate your own network from being at fault during your investigations
Usage
Enter a hostname, IPv4 or IPv6 address in the "Hostname or IP address" field.
To ping a server if you don't know its IP address, enter its hostname (e.g. www.google.com) and select whether to use an IPv4 or IPv6 connection for the ping. If you select IPv6, the hostname must have an IPv6 (AAAA) DNS record.
To ping a server using its IPv4 address, enter the IP address and ensure the IPv4 option is selected.
To ping a server using its IPv6 address, enter the IP address and ensure the IPv6 option is selected.
The ping tool will send 4 packets to the destination address you provided.
Results
A successful ping result will be displayed in green. The following example shows a successful ping result to www.google.com.
You can see that 4 packets were transmitted, and all 4 had a response back from www.google.com - resulting in no packet loss.
PING www.google.com (172.217.26.196) 56(84) bytes of data.

An IP address is an "address" for any device that is connected to a network - a computer, phone, tablet or even a smart fridge. It's how the Internet knows where to send your web pages, email and streaming music, in the same way a postal address tells your mail-person where to deliver your mail.
There are 2 types of IP address currently in widespread use today - IPv4 (the most common) and IPv6 (a newer standard for an ever-expanding Internet.)
IPv4
IPv4 addresses are four groups of between 1 and 3 digits, separated by dots.
For example, the server that runs Solid Tools for Developers has the IPv4 address: 109.228.50.239.
IPv6
IPv6 addresses are longer than IPv4 and contain letters as well as numbers. IPv6 networks can accommodate a significantly larger number of devices than IPv4 networks and are growing in popularity.
For example, the server that runs Solid Tools for Developers has the IPv6 address: 2a00:da00:1800:15a::1.
Open Port Checker
Check if a port on your device is open to the Internet (or not.)
About the Open Port Checker tool
Most Internet-based applications, such as websites, communicate using a TCP/IP endpoint - that is, an IP address and port number.
If a remote computer cannot connect to your application or website's port number, it will be unable to use it.
Ports can be blocked using hardware- or software-based firewalls, which can restrict access conditionally based on the IP address or machine that is trying to connect.
Use Cases
Use the Open Port Checker tool on Solid Tools for Developers to:
- See if your application's port can be accessed from the Internet
- Check if your firewall is correctly blocking an unknown IP address
Usage
Enter a hostname, IPv4 or IPv6 address in the "Hostname or IP address" field.
To connect to a server if you don't know its IP address, enter its hostname (e.g. www.google.com) and select whether to use an IPv4 or IPv6 connection. If you select IPv6, the hostname must have an IPv6 (AAAA) DNS record.
To connect to a server using its IPv4 address, enter the IP address and ensure the IPv4 option is selected.
To connect to a server using its IPv6 address, enter the IP address and ensure the IPv6 option is selected.
Select one of the common TCP/IP port numbers from the list, or enter your own port number to connect to.
Results
A successful connection will be displayed in green. This means the Solid Tools for Developers was successfully able to connect to the port - the port is open.
A failed connection will be displayed in red. This means the Solid Tools for Developers was unable to connect to the port - the port is either blocked or the application is not listening.
Traceroute
Track how packets traverse the Internet.
About the Trace Route tool
Network packets traverse the global Internet by "hopping" from one router to another.
Every router knows where it needs to send a packet next to reach its destination, by using routing tables that are dynamically shared across the Internet.
Examining the hops a packet takes to reach its destination can give an indication of where a fault lies.
Use Cases
Use the Trace Route tool on Solid Tools for Developers to:
- See the path a packet takes from the Solid Tools for Developers server to an IP address
- Find out where a fault may lie in reaching your IP address from an external network
Usage
Enter a hostname, IPv4 or IPv6 address in the "Hostname or IP address" field.
To trace the route to a server if you don't know its IP address, enter its hostname (e.g. www.google.com) and select whether to use an IPv4 or IPv6 connection. If you select IPv6, the hostname must have an IPv6 (AAAA) DNS record.
To trace the route to a server using its IPv4 address, enter the IP address and ensure the IPv4 option is selected.
To trace the route to a server using its IPv6 address, enter the IP address and ensure the IPv6 option is selected.
Results
The raw output from the "mtr" command will be displayed. The following example shows a traceroute to www.google.com.
Each line represents another "hop" in the packet's journey.
Hop number 1 is the Solid Tools for Developers server's upstream router. The final hop is the last known position of the packet, which will be the final destination if the trace successful reached the target.
The time displayed is a cumulative elapsed time from when the packet was transmitted.
