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 (1) IP address.

In assigning IP address space to end users, LaNet 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.

We encourage 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

RFCS can be looked up at this site http://www.ietf.org/rfc.html

IP address spaces can be obtained by either of the following methods. Allow at least 3 weeks if making the request by postal mail.

• LaNet

If you require less than eight (8) Class C networks to satisfy your request you may make your request to the LaNet NOC. Note that all requests for IP Addresses will require written justification.

Contact the LaNet NOC at (225) 219-4860 or otm-noc@listserv.doa.la.gov for clarification if needed when making your request.

IP Addresses are only available to LaNet subscribers. There are no fees charged for use of IP Addresses.

IP Addresses issued by LaNet NOC are the property of OTM.  In the event of cancellation of LaNet services, addresses must be returned (use discontinued) within 30 days of cancellation of LaNet services.

• American Registry for Internet Numbers (ARIN)

If you require eight (8) or more Class C networks to satisfy your request you may make your request to the ARIN.

This is the organization 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:
