ABSTRACT

In this chapter, we study a simple scheme for location management of nomadic hosts on the Internet by using the existing Domain Name System (DNS) infrastructure. Most applications contact hosts on the Internet by using a Fully Qualified Host Name (FQHN) instead of the host’s Internet Protocol (IP) number. The scheme presented in this chapter outlines a mechanism for dynamically updating the DNS server’s name-to-IP mapping for the nomadic host thereby facilitating direct communication between the nomadic host and other hosts on the Internet. We outline the scheme and present the results of two experiments that were conducted to study the scalability and limitations of the scheme.
