Waiting for adblockers.opera-mini.net...

As you can see, this is from Opera "status bar" at bottom left.

The thing is, sometimes it just hangs there, waiting, and takes a lot of time to load any page, even though I'm not using the built in Opera adblocker..

So why this is happening?

Thx..

Opera ad-blocker works locally in desktops.

Also that address doesn't eve seem to be a valid one.

Do you see the complete address? adblockers.opera-mini.net doesn't seem to exist.

This address exists, somehow, we just don't know what it does...

This address exists

Well, my ISP's DNS server doesn't seem to find an IP address for it. Also some IP lookup pages say that that url has no IP address.

Sorry, there was a problem.
adblockers.opera-mini.net has no A records.

http://ip-lookup.net/domain.php

No IP address found for the domain 'adblockers.opera-mini.net'
(no DNS answer).

https://cachecheck.opendns.com/

None of our locations could resolve this domain

This is a mistery.

A mystery which can be easily solved. First we look at the opera-mini.net domain in the WHOIS database:

Domain Name: OPERA-MINI.NET
Registrar: GODADDY.COM, LLC
Sponsoring Registrar IANA ID: 146
Whois Server: whois.godaddy.com
Referral URL: http://www.godaddy.com
Name Server: NIC1.OPERA.COM
Name Server: NIC2.OPERA.NO
Name Server: NIC3.OPERA.COM
Name Server: NIC4.OPERA.COM

So then I'll simply ask nic1.opera.com for this name. And then we get to see something odd happening:

macron:/home/peter $ dig @nic1.opera.com adblockers.opera-mini.net

; <<>> DiG 9.9.9-P6 <<>> @nic1.opera.com adblockers.opera-mini.net
; (1 server found)
;; global options: +cmd
;; Got answer:

As you can see it didn't give me an answer (which is odd because this is supposed to be the authoritive DNS server) because the server thinks I'm trying to do a recursive lookup. In other words: trying to look up a domain which isn't hosted by the server, yet it should be.

When I try to do a regular lookup (using my local DNS server) then I get something similar:

macron:/home/peter $ dig adblockers.opera-mini.net

; <<>> DiG 9.9.9-P6 <<>> adblockers.opera-mini.net
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 26962

So bottom line: this name does not exist. But it also seems the DNS servers aren't properly configured either.
