Using less memory to look up IP addresses in Mess With DNS
A while back I set GOMEMLIMIT to 250MB to try to make sure the garbage collector ran if Mess With DNS used more than 250MB of memory, and I think this helped but it didn’t solve everything. It turns out that I’m not the only one who felt that net.IP was using an unnecessary amount of memory – in 2021 the folks at Tailscale released a new IP address library for Go which solves this and many other issues. It’s always such a great feeling when I think “hey, I don’t like this, there must be a better way” and then immediately discover that someone has already made the exact thing I want, thought about it a lot more than me, and implemented it much better than I would have.
