| Several profiles of users typically require different solutions for remote connectivity. For each of these profiles, a different solution and possibly a different level of support might be required to meet their remote access needs: Full-time telecommuters usually are supported with enough IP addresses to meet their requirements. For them, /32 with NAT, /30, or even /29 address space can be assigned. Day extenders use their home environment as an extension to the existing office environment. They are connected an average of two to four hours to the corporate network, usually exchanging e-mails, downloading or uploading files from the server, or browsing the Internet. Road warriors typically spend most of their workday out of the office traveling to multiple locations. They require a mobile or wireless solution to access their applications on the network. Engineers might extend their office/lab environment at home. If this is the case, they can require up to a /28 IP address space to accommodate their requirements.
Another possible classification here is based on the user's job instead of whether they are full-time or part-time telecommuters. A full-time telecommuter doing HR or marketing work probably will not need five IP addresses, and a part-time engineer might still need a /29, /28, or maybe a NAT private network. |
