Ages 0-5: “Media and Young Minds” https://pediatrics.aappublications.org/content/early/2016/10/19/peds.2016-2591
The chief factor that facilitates toddlers’ learning from commercial media (starting around 15 months of age) is parents watching with them and reteaching the content.
Ages 2-5: No more than one (1) hour a day.

Internet Safety¶
Academia created the Internet and the World Wide Web for sharing academic information; in ASCII.
Sometimes, the best thing to do is to format or totally reset a computer. Before formatting, you should backup or have already backed up important data.
OpenDNS, Google Family Link, and Amazon FreeTime are examples of family-safe internet filter services that do their best to avoid censoring the freedom of information necessary for a functioning democracy.
Sometimes there a bad things in the world that moms and dads need to know about in order to make good decisions.
Cybersecurity for all ages¶
OWASP Juice Shop¶
OWASP Juice Shop is a deliberately vulnerable web application written with Node.js.
“Pwning OWASP Juice Shop” is the official companion guide for this project. It will give you a complete overview of the vulnerabilities found in the application including hints how to spot and exploit them. In the appendix you will even find complete step-by-step solutions to every challenge.
To run the Juice Shop application on your local machine where you may have record of authorized permission to hack:
Install Docker
Run the Juice Shop Docker container:
docker run --rm --name=js -p 3000:3000 bkimminich/juice-shop # <Ctrl-C>
Open your browser to http://localhost:3000/
Read and work through the book: https://pwning.owasp-juice.shop/
Internet Privacy¶
Regardless of the language in a site’s privacy policy, assuming privacy on the internet is a bad assumption due to: legally authorized requests for information, security vulnerabilities,
Information asymmetry is an assumption that tends not to hold over time. Is quantum information ever lost?
https://en.wikipedia.org/wiki/Black_hole_information_paradox
“Why Quantum Information is Never Destroyed | [PBS] Space Time” https://www.youtube.com/watch?v=HF-9Dy6iB_4
In the US, ISPs can sell internet usage history. There was a bill specifically prohibiting such sale, which has since been cancelled by the current FCC administration.
Law, Terms of Service, and Privacy Policies define how you and your kids’ information can be used to pay for the cost of a service.
There is need to investigate the world.
There is need to keep people safe.

DNS Content Filtering¶
DNS domain names are resolved to IP addresses by sending a request to and receiving a reply from a DNS nameserver.
DNS is used to lookup an IPv4 (“A record”) or an IPv6 (“AAAA record” / “quad-a record”) address (“127.0.0.1”, “::1”) for a domain name (“localhost.org”).
Most systems will attempt to lookup the IP address for a domain name from a local
/etc/hostsorC:\Windows\System32\Drivers\etc\hostsfile before sending a request to one of the DNS nameservers listed in/etc/resolv.conf.Instead of everyone regularly downloading an
/etc/hostsfile containing every domain and IP, we have DNS.DNS is an OSI Layer 7 (“application layer”) network protocol for cached distributed key-value lookup that’s just about as old as the internet.
DNS records are typically cached (stored locally) on first request: a DNS resolver cache is typically not flushed until the browser and/or operating system are restarted. DNS lookups will be served from the local cache until the DNS record TTL expires or the cache is flushed.
DNS nameserver IPs can be set on the router and/or on a particular machine.
DNS nameserver addresses can be set manually or automatically from whatever is listed in a DHCP response.
When a device connects to a network, it broadcasts a request for a DHCP server (“DHCPDiscover”). The router or gateway runs a DHCP server daemon process which replies to the DHCPDiscover request with a DHCP response (“DHCPOffer”) that contains a unique IP address for the requesting device to assign to itself, a subnet from which IP routes can be created, a gateway IP to use as the default route, one or more DNS nameserver IPs, and maybe an NTP time server address.
Typically, when a router gets a public IP from the ISP over DHCP, it also receives the ISP’s DNS nameserver IPs; which it will use by default itself and relay requests to on behalf of devices on the LAN which request DNS.
Depending on the operating system, you may need admin rights to change the DNS nameserver IPs for a given connection for a given user.
HTTP and HTTPS connections may lookup the server’s IP with DNS or connect directly to an IP (in which case no DNS resolution occurs and so no DNS content filtering can occur).
A VPN, DNS over HTTPS (DoH), and DNS over TLS (DoT) can bypass any DNS resolver configuration on the router or the device.
Many (free) wireless hotspots will not work with custom DNS resolver IPs because of the way their captive portal attempts to redirect any request for any URL to the hotspot login page.
In the US, ISPs are allowed to sell customers’ DNS usage history (regardless of the unknown age of the user(s))
There are third-party DNS services which pledge not to sell DNS usage history.
