  • 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.






  • OK, here’s how it happened.

    I was hungry, and I wanted to see the menu for my local pizza joint. I couldn’t find it anywhere.

    I discovered that all their socials linked to a website that wouldn’t load. When I checked, the domain had lapsed.

    Out of frustration, I purchased the domain and pulled the last snapshot of their website off archive.org. It had their full menu as a PDF.

    6 months later and it’s still getting visitors from their facebook page, who are viewing the menu. They haven’t even realised.
