  • Well it’s not a scam. It works exactly as advertised. But, just like in casinos, the house is always the winner.

    I made a multi-threaded UK lottery simulator that draws 68 million lotteries per second on my machine. It shows the ROI on average is around 30% meaning the “house” (lottery company/government/charities) gets 70%. Here’s the last line after 5.1billion draws:

    Draws: 5,130,046,351. 3: 56,022,165, 4: 2,521,545, 5: 38,525 5+b 5,918 Jackpots: 113. Losses: 2,491,081,393. Cost £10,260,092,702, Winnings £3,058,100,000 ROI: 29.810%. 68,548,225.400 draws/s

    Yes that means you will wait on average 45.4 million draws before you hit the jackpot.

    In any case. You could implement the meme like the lottery and make money and I assure you, if you made the full info public people WOULD send you money and you’d keep the 70%…










  • Actually how is your ISP giving out IPs to you? Mine uses IPv6 PD to give me a /48. And I then use SLAAC locally on the first /64 prefix on my LAN. Plus another /64 for VPN connections.

    If you mean receiving RA/ND packets from your ISP (which are used to announce IPv6 prefixes) then you need to allow icmpv6 packets (if you don’t want to be able to be pinged, just block echo requests, ICMP in v4 and v6 carry important messages otherwise).

    If your ISP uses DHCPv6 Prefix delegation you will need to allow packets to UDP port 546 and run a DHCPv6 client capable of handling PD messages.

    If you have a fixed prefix, then you probably don’t need to use your ISPs SLAAC at all. You could just put your router on a fixed IP as <yourprefix>::1 and then have your router create RA/ND packets (radvd package in linux, not sure what it would be on pfsense) and assign IPs within your network that way.

    If you have a dynamic prefix… It’s a problem I guess. But probably someone has done it and a google search will turn up how they handled it.

    EDIT: Just clarified that the RA/ND packets advertise prefixes, not assign addresses.


  • I believe the privacy concerns are made moot if all consumer level routers by default blocked incoming untracked connections and you need to poke holes in the firewall for the ports you need.

    Having said that, even knowing the prefix it’s a huge address space to port scan through. So it’s pretty secure too with privacy extensions enabled.

    But for sure the onus is on the router makers for now.






  • Whenever anyone asks if I use AI. My answer is that, so far it hasn’t ever delivered working code. However the majority of times I used it, the code it did provide sent me in the right direction.

    So it’s not useless. And I know tools have gotten better. But when I see companies seriously talking “AI first” and wanting vibe coding to be a main development strategy. I do really worry.


  • The big websites are operating on ipv6. If you want to run your own website it’s actually trivial to host it on both ipv4/ipv6 now and most good hosting providers will give you a /64 allocation.

    In the UK broadband providers also are quite commonly providing IPv6 as standard (albeit the scummy ones dynamically assign a prefix, for absolutely zero reason aside from annoyance). My provider uses PD to assign a /48 even.

    So, really not sure why it’s so slow going elsewhere. There’s really no reason for it now in 2025.
