ISP Lookup
Which provider an address belongs to: the network that routes it, the organisation that holds it, and what kind of network it is.

The provider is the network that announces the address in BGP. A business or a hosting customer may use addresses of their provider; the provider is still the network shown here.
An internet service provider (ISP) runs a network — an autonomous system with its own AS number — and announces the address blocks it serves in BGP, the routing protocol that connects the internet’s networks. The lookup finds the most specific route that covers the address in our copy of the global routing table, names the network that originates it, and adds what the operator declares about itself in PeeringDB (cable/DSL/ISP, content, enterprise, education …).
The registry record is a separate fact: it says which regional internet registry delegated the block, to a holder in which country. For most home connections in Estonia the registry is the RIPE NCC and the network is the provider you pay — Telia, Elisa or a regional operator. For a server it is usually a hosting company or a cloud provider; addresses inside ranges that AWS, Google Cloud or another provider publish as their own are labelled as such.
You can also type part of a name (Telia, Elisa, Zone) to search every AS name we hold.
Frequently asked questions
Is the ISP the same as the owner of the address?
Often, but not always. The ISP is the network that announces the address on the internet; the registry may list a different holder, for example a company that received the block and has a provider route it.
Why does my mobile connection show a different provider than my home connection?
They are different networks. Mobile operators often run their mobile data network under a separate AS number or route it through a different part of their network.
Can the ISP lookup tell me who uses an address?
No. It identifies the network. Only the provider can link an address to a subscriber, and in Estonia it shares that only under legal process.
