  • I’ve got 3 subnets on an L2 switch. You will have clashes over DHCP if you have both broadcasting on the same L2 switch without VLANs.

    My guest wifi is on a vlan, but the switch is L2 and it’s fine. The router has separate physical ports for each subnet. The “guest” subnet is only accessible over Wifi, and the access points are configured so that the guest VLAN is mapped to a separate SSID.

    My third subnet has no VLAN. It’s IPv6-only and all devices have a static IP address. It’s only used for security cameras. I did this so they don’t transmit on the same physical cables as my primary subnet. It is otherwise insecure, as I can join the subnet by simply assigning myself a static address in the same range.

    Note: There is a bug in Windows where it will join an IPv6 subnet on a different VLAN. I had to tweak my DHCPv6 / radvd so that Windows would ignore it. Yes, Windows is this dumb.




  • I didn’t tell ChatGPT who I am. I have a separate email address for it and everything.

    Just keep in back of mind how everything is being linked and profiled behind the scenes. Without anything else, all they have to link you to other things is an IP address and an email. IP addresses aren’t terribly reliable these days. There may be supercookie/fingerprinting mischief going on though.




  • My server is always my old desktop hardware. It’s a 4th-gen i5 with 16GB RAM and it’s keeping up fine. I have thrown quite a lot of work at it too. If you avoid containers, you can serve 20 services off it no problem.

    I too, was worried about power costs. Every time I do the maths, the new hardware will be obsolete by the time I make the money back in savings. If you’re concerned about environmental impact, the initial manufacture of hardware does more damage than running it over its lifetime.

    Dedicated (1U rackmount) servers are always loud and power-hungry. I they idle at 130w and sound like a hairdryer that’s been left on.
