Answer 2

As a customer how can I access the Data Sets licensed?

The Subscriber shall choose between two options to access the data sets. The first and preferred method is via IP authentication, as it is the most convenient option for both Subscribers and LAPOP. The second is using a username and password to log in. Either option is only for use by the Subscriber and its Authorized Users. The username and password will allow for unlimited simultaneous users. The username and password will expire upon termination of the agreement.

What are the IP Authentication Requirements?

Subscriber must have a fixed IP address or range of IP addresses through which it connects to the internet (individual computers may have dynamic server-assigned addresses as long as they use a gateway with a static address to access the internet). Dial-up access and most home broadband services are not suitable. Ideally Subscriber should have a website/intranet from which there can be a link to the AmericasBarometer data base. Bear in mind that anyone who has access to a computer within the specified range can access the AmericasBarometer.

Once your IP address(es) or IP range(s) are sent to LAPOP, Subscriber access will be set up via IP authentication.

What kind of formatting should I use while I send IP addresses/ranges?

1. ALL IP address ranges *MUST* be sent in CIDR format. Address ranges not
expressed in CIDR notation will not be added. The only exception to this is for a specific
address that does not constitute a range.
2. NO address ranges will be accepted that do not span the entire range of the fourth
octet. The entire fourth octet must be represented in the address range, unless an
institution does not have actual ownership of those addresses. As an example, an
institution owning the entire range 192.168.0.0/24 may *NOT* submit a request for
192.168.0.0-17 - 192.168.0.29-255, expressed in its respective CIDR format.
3. CIDR-formatted addresses must be represented as one address or address range per
line.
4. Addresses that can be expressed by a CIDR-formatted range should not be listed
individually. These addresses must be represented by a CIDR-formatted address range.

How can I send IP address(es) or IP range(s) are sent to LAPOP?

If you would like to send that information at the same time of the ordering, you can include that information in the "Order Comments" section of the checkout cart.

Otherwise, you can email the information in the format to ...@vanderbilt.edu
