Toob FTTP

Toob has been installed and up and running for 7 days now.

I really wanted a static IP but Toob charge £8 per month for this.
That's hiking the monthly charge by 32%! So I didn't go for it.

In my router logs I see "Internet connection renewed successfully ....."
at the same time (within a few seconds) each day. Yet my IP address has
not changed since the installation.

Anyone else using Toob who can add an observation?

Even though you are not on a guaranteed fixed IP address more often than
not you will renew with exactly the same one.

I have had the same 'non-fixed' address from VM for at least a decade!

Encouraging!

I run my own mailserver but openly admit that it's not really necessary.
Truth is, I simply like sending e-mail as if it were tracked and
signed for Royal Mail! No one can claim they didn't get my e-mail. I
can prove that is was popped through their letterbox, up to them whether
they opened the envelope and read it or not. Once, nearly 20 years ago
I did produce part of a log showing that my mail had been received and
consequently won the court case.

The IP I currently have has been added to my DNS SPF Record and mail
continues to flow to those usually tricky recipients whose incoming mail
passes through MS servers. I'd be happy to update the SPF record every
couple of months if needed but not more frequently.

What reverse DNS does Toob return for your IP addr? Many mail servers will
refuse to deal with your server if the name includes tell-tale words such as
"dsl" or "dynamic" or "home"

you are paying to escape CGNAT...

It would only change if it failed to renew.

If your router shows its IP address is 100.x.x.x then its likely its a
CGNAT address and its not externally visible or accessible. If you go to
a site like WhatsMyIP.org you will see the address it returns differs
from this.

seeing as there are many IP addresses available in the portion of
100.x.x.x allocated to CGNAT there is no need to rotate addresses.

I don't use toob, but I do use another FTTP provider, albeit in Spain,
but their setup is typical of that used by new entrants to the IP space.
My router shows 100.77.220.118 but external sites see 85.217.147.98

Thank you, helpful and spot on!

My router shows "Internet connection renewed successfully to a 100.?.?.?
address whilst my externally visible address is different.

Let's see how long before the daily renew fails and I get a different
external IP.

Interestingly it includes the last two parts of my current IP address
which is 145.40.133.52 Pretty long odds on that being a coincidence.

So if you have CGNAT you won't be able to receive incoming mails over IPv4,
because there's no route to you from the internet.

You (hopefully) have a public IPv6 prefix that you can use - does your
router get an IPv6 address, and does it change?

(Typically your ISP would give you 2^64 or 2^72 globally routable IPv6 addresses
that you're free to assign as you wish, so it's only the first 64 or 56 bits
respectively of the address that matter as far as routing to your network)

Understood. I've never bothered with receiving mail by SMTP since the
early days of Demon Internet when it was the default. It's sending only
which I prefer.

Although Toob to claim IPv6 support, I've never managed to get my router to connect/receive an IPv6 address with them :-(
