However, in some cases, it become a problem when the user's current location cannot be distinguished. So, a configuration method that changes relation of the subnet IP address and VLAN-IDs at each site has been proposed. But, when a user moves the site, his/her terminal is not connected to the same subnet. In this paper, we propose a location free network system that the user is possible to connect to the same subnet and is identified the location from a source IP address of the terminal by configuring a NAT router and a DHCP server dynamically, even if the user moves the site. We confirmed the effectiveness by evaluating the prototype system.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"797","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"788","bibliographicIssueDates":{"bibliographicIssueDate":"2015-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":141390,"updated":"2025-01-20T19:23:46.731875+00:00","links":{},"created":"2025-01-19T00:18:58.929242+00:00"}
