DNSNAv4: DNS Name Autoconfiguration for Internet-of-Things Devices in IPv4 Networks

Abstract

This paper proposes a Domain Name System (DNS) Name Autoconfiguration called DNSNAv4 for Internet-of-Things (IoT) Devices in Internet Protocol (IP) version 4 (IPv4). The manual configuration of domain names of devices might be a cumbersome burden for users as the number of devices increases. A legacy scheme called DNS Name Autoconfiguration (DNSNA) for IPv6 networks can be used to register DNS names of IPv6 IoT devices automatically into a DNS system. However, the legacy scheme called DNSNA is not applicable in the current networks because most of networks in the Internet are mostly set up for IPv4. In this paper, we propose DNSNAv4 to support suitable functionality to let the legacy scheme of DNSNA provide DNS naming services to IoT devices in the IPv4 environment. In DNSNAv4, an IoT device can register devices by interacting with a dynamic host configuration protocol (DHCP) server so that the devices can register their DNS names and the corresponding IPv4 addresses into a DNS server through a DHCP server. Therefore, with the standard protocol of DHCP, DNSNAv4 can provide users with easy DNS name autoconfiguration of their IoT devices in the IPv4 environment.
