Did Netlify’s load balancer IP address change?

In the documentation Configure external DNS for a custom domain | Netlify Docs you write:

Point the record to Netlify’s load balancer IP address:

Is this IP address still correct?

No change, that’s still the main intended “A” record you’d use where you need one.

As we’ve pointed out in a few dozen Support Guides, you would only use that where a CNAME is not possible (on a bare domain, or the apex of a subdomain you delegate), and only while using external DNS hosting for your hostname(s). (Our own DNS hosting creates superior records on even the bare domain, in case you use it instead.)

Are you seeing some problem with it, or did you see conflicting information somewhere? If so, please let us know more :slight_smile:

I had these DNS settings:

zemtu.com A
www.zemtu.com CNAME zemtu-website.netlify.app

and got these SSL certificate errors when visiting the domain apex https://zemtu.com

:wave: @zemtu

Looks like you have an inactive DNS zone since your name servers are not pointing to Netlify:

% whois zemtu.com | grep "Name Server" 

You’ll need to delete the DNS zone or activate it before Let’s Encrypt can provision the SSL cert.

Hope this helps!

I pressed the button “Delete DNS zone”. Now the urlhttps://app.netlify.com/teams/zemtu/dns/zemtu.com#delete-dns-zone returnes “Page not found” which is good I think. At Netlify App it looks good. The current DNS settings are:

zemtu.com A
www.zemtu.com CNAME zemtu-website.netlify.app

but https://zemtu.com still shows the SSL certificate error:

So I need to change the A record to make it work again for now.

Is there still a wrong configuration on Netlify?

The A records are not pointing to Netlify:

% host zemtu.com
zemtu.com has address
zemtu.com has IPv6 address 2a00:1158:5:570::

You’ll want to delete those two records and create an A record pointing to Netlify’s load balancer IP address:

I currently see

host zemtu.com
zemtu.com has address
zemtu.com has IPv6 address 2a00:1158:5:570::

I currently see the SSL error. I had to revert it to The TTL is 30 minutes here.

hi @zemtu

You no longer have the inactive DNSZone which is good. But now you seem to be pointing to that IP that does not belong to Netlify.

What IP is that? The certificate seems to be active and working now.

Hi, I now made a test with the domain apex tempdomain.at and added this DNS record on our Nameserver:

tempdomain.at A

https://tempdomain.at seems to work as expected.

I’m reluctant to try it again with the domain apex zemtu.com though because it didn’t work the last time.

Are there any (DNS) settings on your side regarding zemtu.com that could cause the problem? Maybe caused by the wrong configuration (DNS zone) we had before?

Hey @zemtu,

I don’t see any reason from our end why your domain won’t work. Unfortunately, till you configure the DNS, there’s no good way to test if it will work or not. Let us know if you have any errors once you do that.

I might have to set the IPv6 address as well. Is this the correct one for the load balancer apex-loadbalancer.netlify.com


Would these DNS entries be correct?

zemtu.com A
zemtu.com AAAA ::ffff:4b02:3c05
www.zemtu.com CNAME zemtu-website.netlify.app

Hi @zemtu ,

The load balancer IP, A and CNAME records are correct :+1: However, we don’t support IPv6 when using our load balancer IP address. You’ll need to remove the AAAA (IPv6) record.
