Acquiring IP Addresses

Acquiring IP Addresses

Guidance

Make sure you have an authorized public IP address space assigned to your organization.

Do not make one up! Remember, every host on your network that runs TCP/IP must have at least one IP address.

In assigning IP address space to end users, the OTS Network section takes guidance from assignment policies and procedures set forth in RFC 2050. These guidelines were developed to meet the needs of the larger Internet community in conserving scarce IPv4 address space and allowing continued use of existing Internet routing technologies.

OTS Network encourages the use of the following address conservation measures where appropriate:

• VSLM (Variable Length Subnet Mask) RFC 2050
• Private / Reserved Addresses RFC 1918
• NAT (Network Address Translation) RFC 1631
• DHCP (Dynamic Host Configuration Protocol) RFC 2131

Additional information can be accessed via the RFC lookup.

Methods to Obtain IP Address Spaces

IP address spaces can be obtained by either of the following methods. 

• OTS Network
  
  • If you require less than eight Class C networks to satisfy your request, you may make your request to the OTS Network section.
  • All requests for IP Addresses will require written justification.
  • Contact OTS at 225.219.4860 or email OTS Network management for instructions
  • IP Addresses are only available to OTS Network subscribers, and there are no fees charged for use of IP Addresses.
  • IP Addresses issued by OTS Network are the property of OTS. In the event of cancellation of OTS Network services, addresses must be returned (use discontinued) within 30 days of cancellation of OTS Network services.
• American Registry for Internet Numbers
  • If you require eight or more Class C networks to satisfy your request, you may make your request to the ARIN.
  • The ARIN organization is charged with, among other things, assisting network administrators in registering IP network addresses. To obtain a network address space you will be required to complete a template, which can be obtained from the ARIN. The template includes instructions on how to complete and submit your request.
  • ARIN can be contacted at:
    • Phone: 703.227.0660
    • Fax: 703.227.0676
