MyIPKit— Your network, explained.

IP Address Lookup

Find out what an IPv4 or IPv6 address is, who it belongs to, and which network announces it.

One IPv4 or IPv6 address. Domain names and URLs are not accepted.

Try:

Lookups are processed on request and are not stored. MyIPKit keeps no record of what you look up.

How to use this tool

Paste a single IP address and select Look up. MyIPKit normalises the address first — an IPv6 address written as 2001:0DB8::0001 becomes 2001:db8::1 — then classifies it and queries the public registries.

Reading the results

Address type

Every address belongs to a range with a defined purpose. Public addresses are routable on the internet and registered to an organisation. Private addresses such as 192.168.1.1 only work inside one network. Others are set aside for documentation, testing, multicast or future use.

ASN and announced prefix

An autonomous system number identifies the network operator that advertises a block of addresses to the rest of the internet. The announced prefix is the block being advertised right now, which is often narrower than the block the registry allocated.

Registration

Registration data comes from RDAP, the protocol that replaced WHOIS. It shows which organisation holds the block, when it was allocated and last updated, and the published abuse contact. MyIPKit shows the abuse contact only, and does not republish other registrant contact details.

Limitations

  • Registration data describes who holds a block of addresses, not who is using one address at a given moment.
  • IP location is approximate. It is often right about the country and frequently wrong about the city, particularly on mobile, satellite, business and VPN connections.
  • MyIPKit does not attempt to detect VPNs, proxies or Tor. Those checks produce probabilities, not facts, and presenting them as certainty would be misleading.
  • Private and reserved addresses are classified locally and never sent to any provider.

What does this tool tell me about an IP address?

Whether the address is public or reserved, which organisation the block is registered to, which autonomous system announces it today, and — when a geolocation provider is configured — its approximate location.

Why does a private address return no owner?

Ranges such as 10.0.0.0/8 and 192.168.0.0/16 are reserved for use inside private networks. Millions of networks use them simultaneously, so there is no registry entry and no location to look up.

Can I look up a domain name here?

No. This tool accepts IP addresses only. Use the DNS Lookup tool to resolve a domain to its addresses, then look up one of those addresses here.
