What runtime are you using?

Bun.sh

It's not supported in Hono directly, bun you can do this

import app from './app';

Bun.serve({
  fetch(req, res) {
    globalThis.ip = res.requestIP(req);
    return app.fetch(req, res)

  },
});

import app from './app';

Bun.serve({
  fetch(req, res) {
    globalThis.ip = res.requestIP(req);
    return app.fetch(req, res)

  },
});

You can acess it with globalThis.ip. Until it's supported in Hono this is the best way @mathys Forget that I found a much better way

import app from './app';

Bun.serve({
  fetch(req, server) {
    return app.fetch(req, { ip: server.requestIP(req)})

  },
});

import app from './app';

Bun.serve({
  fetch(req, server) {
    return app.fetch(req, { ip: server.requestIP(req)})

  },
});

Now you can access it in c.env

@Nico it's working for me with this return

{
  address: "::1",
  family: "IPv6",
  port: 64615,
}

{
  address: "::1",
  family: "IPv6",
  port: 64615,
}

I think you should add this to the doc maybe

Perfect, once it’s live it will show an ip ::1 is just localhost. Or if you use another device you should see it And I will add it to the docs
