ipconfig (standing for "Internet Protocol configuration") is a console application program of some computer operating systems that displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.

Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
It can serve the names of local machines which are not in the global DNS. dnsmasq's DHCP server supports static and dynamic DHCP leases, multiple networks and IP address ranges. The DHCP server integrates with the DNS server and allows local machines with DHCP-allocated addresses to appear in the DNS.
The presence of the OPT in the request signifies a newer requester that knows what to do with an OPT in the response. The OPT pseudo-record provides space for up to 16 flags and it extends the space for the response code. The overall size of the UDP packet and the version number (at present 0) are contained in the OPT record. A variable length ...
