About Ireland IP Address Ranges
IP address ranges are allocated to countries through Regional Internet Registries (RIRs). These organizations assign blocks of IP addresses to Internet Service Providers (ISPs) and organizations within each country. The data shown here is compiled from multiple sources including RIR delegation files, BGP routing data, and IP geolocation databases.
How Are IP Addresses Allocated?
The Internet Assigned Numbers Authority (IANA) distributes large IP blocks to five Regional Internet Registries: ARIN (North America), RIPE NCC (Europe/Middle East), APNIC (Asia-Pacific), LACNIC (Latin America), and AFRINIC (Africa). Each RIR then allocates smaller blocks to ISPs and organizations in their region.
Using This Data
Country-level IP ranges are useful for geographic content delivery, compliance with regional regulations, and network analysis. For programmatic access to IP geolocation data, use the Iploc API which provides country, city, ISP, and ASN data for any IP address.
