For info, Teckk mentioned in their earlier post that they set Firefox to open with a blank page. I'm not sure that caching was included in the Mozilla page about turning off auto connections whose instructions Teckk followed, but prefetching was.

There's a possibility that these are calls to Amazon Web Services or other CDN services.
If you can use this. I needed to find a list of them a while back.
Code:
#! /usr/bin/env python 

#Get AWS IP4 addresses

import requests

url = 'https://ip-ranges.amazonaws.com/ip-ranges.json'

def GetAmazon():
    ip_ranges = requests.get(url).json()['prefixes']

                    if item["service"] == "AMAZON"]) 
                    
    ec2_ips = ([item['ip_prefix'] for item in ip_ranges 
                    if item["service"] == "EC2"]) 
                    
    amazon_ips_less_ec2 = [] 

    for ip in amazon_ips:
        if (ip not in ec2_ips) and (ip not in amazon_ips_less_ec2):
           amazon_ips_less_ec2.append(ip) 

    def ip_to_tuple(ip_str):
        ip = ip_str.split('/')[0]
        ip = ip.split('.')
        return tuple(map(int, ip))

    sorted_list = (sorted(amazon_ips_less_ec2, key=ip_to_tuple))

    for i in sorted_list:
        with open('amazon_ip.txt','a') as f:
            f.write((i)+ '\n')
    print ("Saved to amazon_ip.txt")

You're welcome. Glad that I could contribute something.

Everything connects to Amazon. I blocked the whole bunch a while back.
That's why I made that python script. But then half of the websites
would not work. Even PBS videos use them.

Work has a piece of hardware from AT&T that connects to the internet.
An arris bgw210-700. It is widely used across the US for fibre
customers. I tried to pick it apart to see how it works.

It has a little hidden web sever in it. That little web server takes
the last free IP address in your DHCP range and uses it for itself.
And it sits there and talks to Amazon and others all day. I made a script
to monitor it, posted it here:
https://bbs.archlinux.org/viewtopic....28996#p1828996

and then some firewall rules in the device itself to block anything to it
or from it. Here is a partial log of what that little web server tries to
send out. Unsolicited. 192.168.0.50 is the address that the device claimed
for itself. It's the last address in the DHCP range of IP's that I set it
up to have. You can change that range to something else, it will take the
last one.

That's when it is idle. Doing nothing. It's not responding to a page request.

Amazon is an advertising/data collection monster, has it's claws in everything. Used to be
that google was the monster. AT&T has partnered with them.

I also don't blame the Firefox devs for making money somehow. Just something that's
good to know.

some of us clicked a few links and did some reading (it's all there in the last few posts) and the answer is quite different.
not sure there's a one word explanation, but if there is it's "captive portal detection".
