The network address is the fixed part of the IP address. The worldwide
leading regulatory board for assigning network addresses is the IANA
(Internet Assigned Numbers Authority). If you require an IP address block,
contact your Internet service provider. Internet service providers should
contact their local higher-level organization:
 APNIC (Asia Pacific Network Information Center) - Asia/Pacific Region
 ARIN (American Registry for Internet Numbers) - Americas and Sub-
Sahara Africa
 LACNIC (Regional Latin-American and Caribbean IP Address Registry) –
