 IP Address Services





Internet Protocol (IP) addresses (under the current version 4) are 32-bit numbers often expressed as 4 octets in "dotted decimal" notation (for example, 192.168.45.230).

If you need an IP address or block of addresses, please contact your Internet service provider (ISP).

Internet Service Providers (ISPs) should contact their upstream registry or their appropriate regional registry at one of the following addresses:

           APNIC (Asia-Pacific Network Information Center)

           ARIN (American Registry for Internet Numbers )

           RIPE NCC (Réseaux IP Européens)
