DNS/nameserver tool for admins, webmasters and people with DNS problems

[jsluiter]

Not many people know, but it is quite easy to diagnose DNS problems. It can (will) save you a lot of time searching for problems doing that more efficient. The domain doctor already is for that, but apparently that is not enough, so some tips here about diagnosing;

Use dig.

That's it

For all *sigh* Windows users; http://members.shaw.ca/nicholas.fong/dig/

For Linux users; install dnsutils and you'll have it (Ubuntu/Debian; apt-get install dnsutils).

For ease of use;

http://www.110mb.com/dig.php

for instance;

http://www.110mb.com/dig.php?url=thefacepaintinglady.co.uk

Not that ns4 does *not* respond to extra domains; that is intentional ; it is meant as a backup for 110mb.com and 911mb.com. Don't use it for extra domains.

Some explaining of the result;

First result is A records, which is

dig domain.com

Look for;

;; ANSWER SECTION:
thefacepaintinglady.co.uk. 85711 IN A 195.242.99.182

the IP behind the A should be one of our boxes. If there are no A or empty A, something is very wrong, but before blaming us, read on;

The second is the NS;

dig NS domain.com

Look for;

;; AUTHORITY SECTION:
thefacepaintinglady.co.uk. 85711 IN NS ns2.110mb.com.
thefacepaintinglady.co.uk. 85711 IN NS ns1.110mb.com.

Extra domains should contain NS ns1 and NS ns2 in this region, native domains (ie username.110mb.com) should contain NS n1, NS ns2, NS ns3, NS ns4.

The next section queries all our nameservers for your domain;

dig @ns1.110mb.com domain.com
dig @ns2.110mb.com domain.com
dig @ns3.110mb.com domain.com
dig @ns4.110mb.com domain.com

Look for;

;; ANSWER SECTION:
thefacepaintinglady.co.uk. 86400 IN A 195.242.99.182

The IP behind the A should be the same for all 4 nameservers. Note that ns4 will not respond for extra domains; that is fine.

Now;

- if the IP is different in the nameservers in the last 4 tests; wait 24 hours
- if the first test does not return an A record with an IP
- - if the second test does not answer with at least NS ns1, NS ns2 ; your domain DNS settings are wrong; fix them
- - any other problem; wait 24 hours then contact an admin here
- if the first test returns the wrong IP
- - the last 4 tests are returning the right; wait 24 hours
- - the second test has the wrong nameservers (no NS ns1, NS ns2) ; your domain DNS settings are wrong; fix them


Have fun

Nice tool. Thanks.

But now Busman will have more free time. Do you plan to fire him?        (joke)

Does this tool require a large amount of server resources? Because this tool may be handy at checking others domains for configurations when problems arise. But if it requires large resources, then I wouldn't want to use it often.

Nevermind. I got the command line version for Windows. Works great:)

[revijapiki]

Can anybody help me with my problem... My second domain www.zastonj.info suddenly disappeared. Primary domain piki.110mb.com however works fine :S They are both present on my control pannel (I didn't change anything recently).

Registraar told me that there is nothing wrong on their side and sends me the following piece of info:
ns1.110mb.com [195.242.99.84] [Broken DNS server: Reports a server failure] 124ms
ns2.110mb.com [195.242.99.98] [Broken DNS server: Reports a server failure] 139ms

Your help would be much appreciated!

All three of the nameservers that handle 'extra domains' were down for ~2 hours.

Try your domain again.

How can u change the name server

[t50webmaster]

How can u change the name server

it depends on your domain registrar
usually there is a spot to edit the dns settings.

[buy-mob]

I had a subdomain at 110mb "http://buy-mob.110mb.com" can i change the name server.

[t50webmaster]

you can not change your subdomain, only a domain that you've purchased from a domain registrar like go-daddy or something like that.
also please don't PM me for help, i do not do private support.

Find something like "Managed DNS" or "Custom DNS". Who is your DNS registrar anyway?

[geordie]

Sorry I'm really clueless with this ........... I've registared with www.110mb.com and my addy is http:/touchmetender.co.za

[Ellimist]

From which website did you register http:/touchmetender.co.za?

[geordie]

I registered it at 110mb.com under the following domain » http://geordie.110mb.com

[Ellimist]

Did you buy anything related to "touchmetender.co.za"? To use the domain "touchmetender.co.za" you need to buy it from some place like this.

I suspect that you didn't register the domain name "touchmetender.co.za", you just added it to the 110MBPanel?

That does seem to be the case..
