System and method of utilizing multiple networks
In one or more embodiments, an information handling system (IHS) may receive, from another IHS via a first network, a dynamic host configuration protocol discovery request, provide, via the first network, a first Internet protocol version four (IPv4) address to the other IHS, and associate a first Internet protocol version six (IPv6) address. The IHS may receive a domain name service (DNS) lookup request from the first information handling system, provide a multicast DNS (mDNS) request, based at least on logical name information from the DNS lookup request, to a second network, and receive a mDNS response that includes a second IPv6 address associated with the logical name information from the DNS lookup request. In response to receiving the mDNS response, the IHS may configure at least one network address translation configuration that associates that associates the second IPv6 address and a second IPv4 address.
