#244182 — cooperative.co.uk has address 127.0.0.1

Why do I see this?

host cooperative.co.uk
cooperative.co.uk has address 127.0.0.1

host cooperative.co.uk 1.1.1.1
Using domain server:
Name: 1.1.1.1
Address: 1.1.1.1#53
Aliases: 

cooperative.co.uk has address 127.0.0.1

cat /etc/hosts|grep -i coop

This has nothing to do with debian other than that I am using debian,
but I am not sure where else I would ask.

Because whoever set up that DNS zone made an error.

unicorn:~$ host cooperative.co.uk

It's only been once or twice, but I've seen it, too. Pondered it for a
few seconds each time then a-sumed it was somehow tied to the other
end running their own server. The afterthought problem with it is the
inevitable collision with others (obviously) doing the same across the
Web.

Thanks for your reply and others.

It doesn't seem like an appropriate use of the address to me, and I
stared in disbelief when I saw it, thinking something had gone wrong.

Even, for example, example.com has its own ip address. Or perhaps they
should have returned an error like an.invalid. I guess they want to
discourage its use but also prevent anyone grabbing it.

This is unlikely to be an explanation for cooperative.co.uk, but it used
to be fashionable to register a vanity domain, set an A record to
127.0.0.1, set the AAAA record to a valid IPv6 address from which you
connect to an IRC network, set the AAAA rdns record to match, and then
you appear on IRC as your chosen vanity host. If you get into an
argument with someone on IRC (perhaps more common for the types of
people who go about setting this up) and the other end decides to packet
flood you, if they aren't careful they'll direct their packet cannons at
127.0.0.1.

It was also fashionable for a while to set up names like ftp.warez.org 
and point them to 127.0.0.1.

I hate to douse the party, but all 127.0.0.0/8 addresses are defined to be
loop back. So no network interface card or network stack on top of it
should write anything to the wire or air to that address.

It's just bored system administrators :-)

…that's entirely consistent with what we wrote. That's the entire point
of the setup I described.

Agreed, …

… and I can't see just how that would alleviate their boredom.

But nobody here has said what cooperative.co.uk pointed to in the past,
if anything. My own relationship with the Coop (bank¹/shopping/divi)
ceased before I started using the internet for personal business, so
it's not something I could look up on old correspondence, stationery etc.

I did wonder if it might ever have pointed to the banking arm of the
Coop, back in the days when the "Coop bank" was part of the Coop. If
that were so, they might want to "sanitise" the domain for a long
period of time rather than have people fetch up at either the Coop
proper, or the now completely separate "Co-operative Bank".

That kind of sanitisation would contrast with, say, the way in which
lloydstsb.co.uk gets treated. Here, the old domain is still
functionally identical to lloydsbank.co.uk even though the TSB part
of Lloyds TSB was spun off years ago into tsb.co.uk.

¹ Their selling point back in the 1980s was free current account
  banking for clubs and societies, something the commercial banks
  charged for. And they even gave you giant cheque books (for
  multiple signatories).

Cheers,
David.

So - the Cooperative Society - is at https://www.coop.co.uk 

It's quite possible that the 127.0.0.1 is genuine to prevent someone else using it and that their webserve rand DNS provision  will redirect cooperative.co.uk
to coop.co.uk in due course.

Hope this helps,

Andy Cater

Oddly, when I searched for "Co-operative Group Limited" (which I got 
from whois), I found a different site: https://co-operative.coop

It seems to be the same people, but a totally independent site.

AFAIK a domain doesn't have to have an A record at all. Or any records 
for that matter; having it registered should be enough to save it.

Why not just redirect it now? Maybe they can't decide which of the above 
sites is the right one :-)

Richard

https://co-operative.coop looks like the parent organization while https://www.coop.co.uk is the supermarket. The "Food" link on the former redirects to the latter.

Because that's the IP that is associated with that name in the DNS.

There may be multiple reasons for that; one is to effectively block all requests
without straining the host that name had been associated with before.
