When I go to iknowwhatyoudownload.com, a bunch of stuff shows up for my IP that’s definitely not being downloaded by anyone in my house (foreign language torrents). Aside from that my router (AT&T Arris BGW210) needs to be restarted about once a week, due to some kind of dhcp issue. The most recent event seemed bad - none of my devices had internet, they could all talk to each other, and my ONT activity light was flickering steadily. During this time I had no access to the router, even plugged in directly to LAN. Fixed by a restart but no idea what was going on.
The DHT torrent thing has been happening for months and the router thing could just be that AT&T sucks. I have no other evidence that something is wrong.
I could buy a firewall and put it downstream of the AT&T equipment.
I could switch internet providers, get a new IP address and router, and see if that fixes it.
Should I try to figure out what’s going on or just keep restarting the router once a week and ignore the DHT hits from my static IP?
Alright, I didn't know ISPs use other types of NAT for the "few to many" mapping of public IPs to customers - all I've seen in my limited experience were plain old static public IPs, dynamic public IPs assigned on each connection, and what I assume to be a CGNAT (the router was assigned an IP in the 100.64.0.0/10 range from the ISP). So that's good to know, thanks.
This has literally nothing to do with my comment.
