It shows your IPv4 and IPv6 addresses and their internet service providers. You can also enter an IP or domain name to find their ISPs. Not as fancy as some startups, but I hope it'll have a tiny impact on many people :) https://isplookup.com27 May 2025 07:39 +0000at://did:plc:bgdyn7yxffog33w2anz7ipnd/app.bsky.feed.post/3lq56pgztfk2phttps://bsky.app/profile/ruurtjan.com/post/3lplvkecq4s2xI don’t understand why people advise junior developers to avoid using AI. They lack experience, but they’re not stupid. Surely they’ll eventually figure the right design.
