Persistently Wrong DNS IPs - Help

Website, Application, Performance DNS & Network

My domain is persistently getting wrongly resolved in most locations like france, pakistan, etc

In these wrong dns mapping my domain gets resolved to 188.114.96.7 (when you do DNS-check online), which is a wrong IP and the resolving always fails.

It is only in the other few locations with the correct mapping of IPs 172.21.19.18 and 172.67.187.117 that successfully resolve my domain.

It has been over a week now and these wrong DNS IPs have persisted in these locations.

Please help on on how i can remove these wrong DNS IPs.

I’m a bit confused here.

Why would this be wrong? It’s a Cloudflare IP.

This is a private IP and I assume is a typo?

It’s wrong because dozens of reports of reachability issues exist for these addresses and Cloudflare support ignores them.

I assume this only impacts free customers and since free customers conveniently can’t raise support tickets they are SOL. I can’t imagine any Enterprise customers are using these IP ranges or it’d actually be fixed.

I thought Cloudflare would just use anycast alone but if different areas around the world are getting different IPs then I guess there’s some EDNS Client Subnet / GeoIP going on with it.

Posts about IP reachability seem to get buried or ignored without much official acknowledgement - whilst it might usually be ISP or upstream issues, it’s not really a sufficient answer for many people.

Just look at people who are paying for Stream - it took them awhile for their videos to be reachable (due to ISPs blocking the domain). Might not be on Cloudflare to tell an ISP what to do but it’s definitely a case where your only option is to accept your customer’s can’t access your content or move to another provider.

What’s the domain name? If this is something that you can replicate then we should be able to get a ticket opened & escalated.

Not wrong per se, but Cloudflare does not show much love for that IP block and they sort of “abandoned” the anycast thingy.

Not the first time.

Yes 188.114.96.7 is a Cloudflare IP but whenever users try to be accessed the site “myvj.net” from that IP (after DNS resolves to it), it always fails; and users are NOT able to access the site.

The lucky ones are only able to access the site when DNS resolves to 172.21.19.18 or 104.21.64.51.

I do not know whether it’s different ISPs around the world simple blocking this IP or it’s a Cloudflare issue
