w3dt.net W3 Domain Tools
When troubleshooting network or DNS problems related to your website, server or other online services it can be very useful to have access to online tools that can help you identify the problems. The useful free tools found at W3dt.net can help you with this. W3dt.net (short for World Wide Web Domain Tools) is an online network troubleshooting site dedicated to providing relevant real-time data regarding networks, websites and other technical resources.
Although you can perform some of the tasks w3dt provide from your computer (such as nslookup/dig, ping, traceroute etc..) it can often be useful to perform these tasks from different locations to verify the consistency of your network/domain, its behaviour and settings.
Firstly let’s note that there are several other network/domain troubleshooting websites around, but w3dt.net has proven to be one of the popular sites due to the vast amount of tools and utilities that are all free of charge. Because of this we will be regularly reviewing some of the functionality of the site and its features.
The site currently has five categories of functionality (and growing) to help you trouble-shoot your network/domain:
- Network Tools / Internet Tools
- Web / HTTP Tools
- Ping Tools
- Database Lookup Tools
- General Tools
Network Tools / Internet Tools
These are generally the most frequently used tools on the website and contain the following features:
- DNS Lookup’s, Port Scanning
- Trace Route’s
- ARBL Checking (Blacklist / Whitelist Checking)
- Maximum Transmission Unit Determination
- IP Lookups
- NetBIOS Scanning
- Plus Much More..
You can run some of these tasks from your desktop computer but w3dt offers the assurance of real-time results without any interception of data.
The following tools can be used to test your Domain in real-time and return the most relevant results:
- HTTP Header Retrievals
- Plain Text Website Conversion
- URL/Base64 Encoding & Decoding
This category basically speaks for itself, w3dt.net has dedicated a whole category for pinging and ping testing. Using this category you can run your own ping tests on any IP/Domain, including http websites, and the ability to ping IP’s/Services on open TCP Ports.
Database Lookup Tools
W3dt.net hosts several large databases, such as RFC Lookups, WHOIS Lookups (on almost all domains on the internet), Abuse Contact Lookups, and most impressively (In my opinion, the biggest feature on the site) the DNL (Short for Domain Name Listing). Basically the DNL is a massive online database of every top level domain hosted on the internet. W3dt runs a query program codenamed “Project Cyberdawn” which spiders through the internet collecting information about every .tld (Top Level Domain) on the internet. Currently the DNL contains over 92 million domains, there is a good chance your domain and the connected public information will be in the database also.
Most of the general tools listed on w3dt.net are used by I.T. gurus & technicians tools such as IP Conversion, Hash Testing, and Random Character / Password Generation can be found here. For instance these tools are great if your a programmer or web developer and you wish to see all 38 hashes for the query ‘dog’ and use them to query against your database.
