How items are structured | Internet Archive Blogs
An item is a logical “thing” that we present on one web page on An item may be one video file along with scans of the DVD cover, one book, one audio file, or a set of audio files that represent a CD , etc.

How do you know whether your files should be in one item or separate items? You get one metadata file per item. If the same metadata describes ALL of the files (like a CD), then that’s one item. If the files are too different to have the same metadata (title, creator, description, etc.), they should be in different items.

NXDOMAIN, NODATA and debugging DNS for dual-stacked hosts - Cisco Umbrella Blog
TL;DR – An NXDOMAIN response means there are no records, of any DNS type, for the requested domain name. A NODATA response means there are records for the requested domain name, but none of them match the record type in your request.

Happy Eyeballs - Wikipedia
Happy Eyeballs (also called Fast Fallback) is an algorithm published by the IETF which can make dual-stack applications (those that understand both IPv4 and IPv6) more responsive to users by attempting to connect using both IPv4 and IPv6 at the same time (preferring IPv6), thus avoiding the usual problems faced by users with imperfect IPv6 connections or setups.

Dynamic DNS - ArchWiki
Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.

The term is used to describe two different concepts. The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing. These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security. The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the RFC2136 standard for updating DNS records. These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently.

Here are my questions:

a) how does the CNAME redirect work when fetching content? does DNS resolve the cloud IP address and allow just one HTTP connection to the cloud or is the HTTP connection sent to my server and then relayed to the cloud? which server presents the SSL cert for I believe that I need to configure a local server to offer the SSL certificate because DNS alone would not suffice, but I am not sure on the architecture.
