Is your domain blocked in Poland? Check it per ISP
ISPs answer with the regulator’s block page · Ministry of Finance (Rejestr Domen)
The provider’s own DNS resolver returns the regulator’s address instead of yours, so the subscriber lands on a warning page while the domain stays perfectly healthy everywhere else.
We confirmed this ourselves: asked Orange Polska’s own resolvers for two domains from the register and both came back as 145.237.235.240 — the Ministry’s warning page — while public DNS returned the real addresses.
What we check in Poland
For every provider below we ask that provider’s own DNS resolver, from inside its network, what your domain resolves to — and compare the answer with public DNS. That is the same answer a subscriber gets, which is why a datacenter-based “is it down?” tool cannot see these blocks at all.
| Provider | Network |
|---|---|
| Orange Polska | AS5617 |
| Netia | AS12741 |
| Polkomtel (Plus) | AS8374 |
| P4 (Play) | AS39603 |
| Vectra | AS21021 |
What a blocked domain looks like here
Instead of your real address, the resolver returns
145.237.235.240.
If you see that address for your own domain, the domain is on the list — your hosting is fine.
The official list
Ministry of Finance (Rejestr Domen) publishes the register at https://hazard.mf.gov.pl/. Domains are added continuously, and nobody tells you when yours is added.
How to check your own domain
ASNWatch runs this check for you every half hour across 5 Poland providers and tells you which one stopped resolving your domain, usually before the traffic drop shows up in your tracker. The free plan covers three domains.
