Hello (into)DNS world!

Adrian Andreias | Tuesday, November 20th, 2007

This blog is about the IntoDNS journey. So let’s get started.

What?

IntoDNS checks the health and configuration of DNS servers and mail servers. It’s designed as a tool that helps server and network administrators in day to day job, to identify and fix DNS and mail issues.

Who?

IntoDNS is developed by a team of professionals from Elvsoft. Cristian Tomoiaga, an experienced system administrator, is the main project developer. Ovidiu Mocan and Adi Boiciuc worked on the graphic design and the clean XHTML & CSS code. Adi Andreias contributes to some of the tests and coordinates the whole project.

How?

We chose Python because it’s an elegant and powerful language with great multithreading support. And multithreading is crucial for IntoDNS’ performance. Django sets the web stage for Python and jQuery helps us with some of the tricks.

Where (are the ads)?

A strong project is a project that can sustain itself. But we don’t like web sites that have more ads then content. We don’t plan to overload intodns.com with screaming ads. When we’ll need a bunch of servers to sustain the traffic we ll probably come up with some sponsorship model with a single, small, nonintrusive and industry related ad. Drop us a line if you want to sustain IntoDNS.

Where to?

We plan to continue to improve IntoDNS and make it the best DNS health checker on the web. Feedback is very important to us. So don’t be shy.

Hi,

Some DNS querys aren’t working ok.
I’ve tested some domains from your tool and they resolve incorrectly the ip’s of the DNS servers.

Best Regards,
Ricardo Fernandes

Do you have specific IP’s we can unblock for IntoDns – LOVE it but the admin blocked various countries and, well, it only kinda works now. If I had the ips, we could have him unblock those. Keep up the great work!

Very impressive. A good clear report which fortunately for me did not show up any problems. We have http://www.guvera.com as the main site and register.guvera.com for pre-registration. We do not intend to have http://www.register.guvera.com so the last report line was not so much an error but a warning. Thanks.

I was looking for a similar website of DNSStuff.com. intoDNS is the one! Actually, I like the design too..

Keep it going!

I assume this project is Romanian since the theme was made by Elvsoft (I could be wrong tho).
I’m willing to support this project if you will ever need a sponsor.
Just drop me a email.

Hi. IntoDNS is a great and powerful tool. You’ve mentioned ensuring it is sustainable and I’m certain no one would have any objection to there being a few Google Adsense links along the bottom.

When something DNS or server related is shown, I’d be glad to get diverted and look at an ad or two… if IntoDNS gets supported and is more viable as a result that’s even better. Richard

Overall a good product. I would include SPF record checks and more specific recomendations rather than ‘this is not so good’

thanks. used one or two others that took 45mins to load, this one quickly pointed out that i forgot to add a third ns record to match the domain’s ns records.
next time i went to do a test (just now) i skipped over all the google results for “whats that site again”

Let’s kill the propagation time!

Changing dns kills a site for 2 to 3 days. That’s not acceptable! Changes should be immediate to an organisation such as google_dns or opendns who would relay the site during propagation. If you agree please start talks with opendns, google, or whoever who would accept the relaying tokens.

Adrian Andreias says:

What I find unacceptable is people writing angry emails related to their DNS not working, world peace and other problems.

If you don’t understand this service, please don’t use it.

Thanks for the great site. Definitely if you need fundage to keep it going consider putting some inobtrusive Google AdSense at the bottom.

If it makes sense, I’d like to see whois information added to the report. It’s not DNS information, but it is a piece of information about a domain that’s useful.

Paul Fuhrmeister says:

February 24th, 2011 at 8:34 pm

I am getting different results for the same domain name based on capitalization. For instance:
http://www.intodns.com/lcafw.org versus
http://www.intodns.com/LCAFW.org

Hi, all! Thanks for the useful site. It is a significant help.

Could you please tell me what the phrase “parent server” means, and in particular with comparison to http://linuxhelp.blogspot.com/2005/09/understanding-domain-name-system-dns.html?

Thanks much. And keep up the good work.

Hi, I really enjoy using intoDNS. Does it check for DNSSEC? I recently setup a few name servers with DNSSEC and was trying to see information on them. If you would like to check out to my DNSSEC name server zones please contact me. Thanks! Jeff

I just discovered the intodns website. Looks great! However, it seems to be IPv4 only. It does not show the IPv6 addresses and IPv6 glue records.

IPv4 is almost exhausted. IANA ran out of addresses last Februari and APNIC last April. Therefore, we are starting to introduce IPv6, but the DNS setup for IPv6 cannot be checked, currently.

IPv6 support would be a very worthy addition!

Fred Zwarts says:

A nice tool to check the DNS setup.
What I am missing, though, is IPv6 support.
Now that IPv4 is almost exhausted (IANA ran out of addresses in Februari and APNIC in April), we are introducing IPv6. It would be nice to have the same checks for the AAAA records as for the A records.
Also a warning if the DNS (or its parents) is not IPv6 ready seems appropriate.

I work for a Hosting company and your site had made my job 30% easier, cheers!

Great service you provide!
Thank you very much!
But I did ran into a problem your site does seem not detect: I had a subdomain where the SOA stated to be within – which will most likely go bad – a friend resolved the (somekind of obvious) problem for me – maybe you should adjoust your script in that way to check SOA is not within the zone – you can mail me for further information.
Cheers!

can you help me

The logic for checking if multiple nameservers are on “Different subnets” and “Different autonomous systems” is flawed.

Eg.,
NS1 = 111.111.123.111
NS2 = 222.222.123.222

it says “WARNING: Not all of your nameservers are in different subnets”
and “WARNING: Single point of failure”

It seems to be checking only the third octet of the IPs, ignoring the first two.

The “send feedback” link on intodns.com doesn’t work !

“Your SOA EXPIRE number is: 3600000. That is NOT OK” What do you base this on? I would like to refer you to http://www.ripe.net/ripe/docs/ripe-203 which recommends this exact value.

Fred Zwarts says:

November 21st, 2011 at 6:50 pm

As I said before, it is a very valuable tool.
Adding some checks to verify the secure DNS setup would be an improvement, though.
