Very strange browser behaviour (firefox) -- probably security related

Hello
I just noticed a very strange behaviour in my browser (Firefox).
It's probably not the correct forum to put this post in so Admin can feel free to put it somewhere else.

I tried to call a site (actually an invalid domainname so it seems) in Firefox and get linked to my localhost. I actually have a local LAMP-Sever to work on my website etcetera.
The site I tried to call was/is hmamail.com.
I supposed it to be the domainname of a disposible Email-Inbox but it is not.
I whether have this domain in Apache sites-enabled nor any clue how this can happen.
It's probably a security related affair so I post it here even if I usually try to avoid that.

If someone has an idea how that can happen I'd appreciate any help.
I have no history enabled in my browser.
I exclusively browse 'private'.

Greets
Gee

i still do not understand what actually happened.
it seems you missed the most important bit in your explanation.

simply spoken...
I call the website hmamail.com (which is invalid, no DNS-Entry) and get returned the localhost hosted website.
Apologies if my English is ambiguous.

That's because hmamail.com resolves to localhost:

Code:

dig +short hmamail.com

127.0.0.1

i get the same.
but why?
this is so weird.
'whois hmamail.com' gives very elaborate output about it being some godaddy site in arizona...

Untrue. See below.

"some GoDaddy site in Arizona" is the Domain Registry.

It makes sense that if you run a proxy anonymizer and want to send email from that same service,
that you as a network and system administrator, set hmamail.com to only resolve to a working
email host from a known host. Not resolvable from the outside. I think it's easily done too, eg:
Set A Records to 127.0.0.1 on the name servers, (theirs are in Amazon's Route 53) DNS service:

Code:

dig A +short hmamail.com @ns-1016.awsdns-63.net

feel free to try a couple more. :)

Code:

host -t ns hmamail.com

hmamail.com name server ns-1016.awsdns-63.net.

hmamail.com name server ns-1072.awsdns-06.org.

hmamail.com name server ns-166.awsdns-20.com.

hmamail.com name server ns-1839.awsdns-37.co.uk

Short version:
On their page/service, the site can resolve hmamail.com and likely authenticates to another email service
to process for delivery as (example) inbound@hmamail.com

Some DNS detective work can be used to make the same conclusion.

Code:

dig MX +short hmamail.com

0 inbound.hmamail.com.

shows us the mail server identifying host(s)

Code:

host inbound.hmamail.com

inbound.hmamail.com has address 96.44.163.218

and that turns out to be on QuadraNet, Inc

It is conceivable that inbound.hmamail.com will only receive mail from hidemyass.com and that via "Trusted Hosts".

Good stuff on a Saturday.

What this has to do with Firefox I have no idea.

DNS.fu

thanks for the clarification!
still somewhat hazy, but that is entirely my own fault...:o

Well, I admit I don't understand; I get

Code:

 Buy this domain.

hnamail.com

..... I don't see how it resolves to 127.0.0.1 for others ...

Apparently it's fixed by now and points to a parking domains page:

Code:

dig hmamail.com +short

54.72.9.51
