DNS Nameserver Response Comparison Tool
DNS Nameserver Response Comparison Tool
Over the years, as we have worked with setting up Nameservers with A records we have found that it can be a rather complex task. So we made a DNS Nameserver Response Comparison Tool.
The work of configuring the servers is straight forward (we prefer to work with Bind on Ubuntu). We have come up with ways of automating the configuration in order to manage the large numbers of domains our Name Servers handle. However when an issue comes up it can take a considerable amount of time to identify differences between the servers.
The time that it takes for records to propagate throughout the internet and simultaneous whois record updates can add confusion.
So, we came up with the Nameserver Results Compare Tool.
- Enter Nameserver 1 and Nameserver 2
- Enter a list of domain names
- Review the results with discrepancies highlighted
The link to the tool is here:

Some other uses of the tool:
- Know whether a new Nameserver correctly reports all of your domain names, before you put it in production
- Compare googles 8.8.8.8 Nameserver results against your own.
- Identify when a recursive name server is caching the results in stead of requesting them from the authoritative source
As of this writing, the tool is new. If it is anything like the Bulk MX and DNS Lookup Tool we will likely add new features as we find new uses for it.
Some of the potential new features we could see for the future:
- Add multiple additional name servers
- Save frequently used name servers
- Add different record types (MX, TXT, CNAME)
- Control and report on the recursive portion of the request
- Track the comparison history

Bulk MX and DNS lookup enhanced
Bulk MX and DNS lookup enhanced
As our bulk MX and DNS tool has become more popular, Google has sent many people to our site looking for all sorts of DNS lookup tools. It seems that I was not the only one that needed a simple way to quickly gather DNS information on multiple domains at once
Many people have been able to quickly find all of the information they need about a domain (A, MX, NS and WHOIS records) and they move on. It turns out that even though the tool had the ability to lookup records for multiple domains at once, it is also useful for getting a quick DNS overview of a single domain. Web professionals often bookmark the tool and come back often.
The tool evolves as we get special requests, so my request to you is: let me know if I can add some functionality to the tool for you.
Several new features have been added in the last month.
- A premium option allows you to buy credits to remove usage limits
- Whois lookups are turned off on larger requests in order to avoid abuse restrictions
- Large scale lookups can be started by uploading a text file with one domain per line.
- For each file upload a background process builds a downloadable CSV file listing one dns record result per lin
- A row for each www and @ A record with the ip address
- One row for each MX record
- One row for each NS record
- One row displaying the ip addresses for each MX record.
- As the process builds the records file in the background , you can refresh the page withe your premium code in it and watch the progress.
Future upgrades may include
- The ability to choose to only lookup certain record types (A, MX or NS)
- Multithreading options to speed up background lookups.
- They ability to choose the download format of the DNS results list.
If you find the tool useful or you would like a certain type of enhancement, please leave a comment or send us a comment.
If you happen to be a techie that has to look at log files with timestamps, take a look at the tool that bulk converts timestamps to readable dates. You can just cut an paste a big block of text from you log and click
