Final answer:
A local DNS service is resolved on an internal network by setting up a DNS server to manage domain name to IP address translations, configuring DNS records, and adjusting device settings to use the local DNS server.
Step-by-step explanation:
Resolving a local DNS service on an internal network involves configuring a DNS server within the network to manage the translation of domain names to IP addresses for devices on the internal network. This DNS server can be a standalone server or integrated into other network infrastructure like a router. To set up a local DNS server, an administrator would specify DNS records such as A records for translating domain names to IPv4 addresses and AAAA records for IPv6 addresses, as well as PTR records for reverse DNS lookups.
Additionally, in some configurations, devices on the network need to have their network settings adjusted to use the local DNS server, usually by setting the preferred DNS server to the IP address of the internal DNS server. Devices would then query the local DNS server first before reaching out to external DNS servers, enabling faster name resolution and the ability to resolve custom internal domain names.
