Any suggestion on getting plain IP address from the request header?

When I use

request.headers.get("CF-Connecting-IP")

request.headers.get("CF-Connecting-IP")

request.headers.get("CF-Connecting-IP")

request.headers.get("CF-Connecting-IP"), in a worker it prints -

"ip": "2a06:98c0:3600::103",

"ip": "2a06:98c0:3600::103",

"ip": "2a06:98c0:3600::103",

"ip": "2a06:98c0:3600::103",

I jut want the plain IP, something like

198.0.0.1

198.0.0.1

198.0.0.1

198.0.0.1

If a user connects via IPv6 then the connecting IP will be an IPv6 one.

That' my IP. when i check on https://whatismyipaddress.com/ it show the IPv4 as well. Any way to convert v6 to v4?

They are 2 entirely different things and you can’t get an IPv4 from IPv6 or vice versa.

Cyb3r-Jak3•12/22/23, 9:11 AM

You’d have to disable IPv6 on your zone to prevent users from connecting via IPv6, but would affect all your other sites. Also think you need pro plan for it.

There is a setting in Network tab, what does that do? I was expecting it will add IPv4 as per the description.

As a stopgap to accelerate the adoption of IPv6, Cloudflare offers Pseudo IPv4 which supports IPv6 addresses in legacy applications expecting IPv4 addresses. The goal is to provide a nearly unique IPv4 address for each IPv6 address, using Class E IPv4 address space, which is designated as experimental and would not normally see traffic

It just generates a fake one

And afaik, since Workers support IPv6, then that won't do anything anyway

HHello, I’m Allie!And afaik, since Workers support IPv6, then that won't do anything anyway

Chaika•12/22/23, 4:28 PM

hmm what do you mean by that? They run behind proxy, you can have V4/V6 only workers ex: https://v4.chaika.me/, https://v6.chaika.me/, have to use Ent Spectrum though.
Free plan can still disable IPv6 last I checked, should make any workers v4 only (on that zone/domain via routes or custom domains). Can't do that for v6 though without Spectrum

Hello, I’m Allie!•12/22/23, 4:31 PM

I meant in that case specifically, since Workers are the "origin"(and they support both), it should still return IPv6

Sanity check, am I allowed to use the Cache API for non-HTML content? i.e. binaries.

dave•12/22/23, 7:08 PM

https://blog.cloudflare.com/updated-tos/

So I know using the Cache API with R2 is definitely allowed... but what about Cache API + Backblaze B2?

IIRC, since Workers is DevPlat, then yes

Finally, we made it clear that customers can serve video and other large files using the CDN so long as that content is hosted by a Cloudflare service like Stream, Images, or R2.

Ahh so the blog says this (no mention of DevPlat), but it looks like you're right when you look here:

https://www.cloudflare.com/service-specific-terms-application-services/

Cloudflare offers specific Paid Services (e.g., the Developer Platform, Images, and Stream) that you must use in order to serve video and other large files via the CDN.

Thanks!

One of my function is waiting for a promise to be resolved. Imagine it took 10 seconds for promise to be resolved in which the network call took 9 seconds to fetch the response. In this case, how much I would be billed for?

1. 1000 milliseconds OR
2. 10,000 milliseconds?

kian•12/23/23, 3:21 AM

Bundled? N/A (doesn't charge by duration)
Unbound? 10s (wall time)
Standard? 1s (CPU time)

ashutosh•12/23/23, 3:27 AM

With Standard pricing.

ashutosh•12/23/23, 3:28 AM

I think Bundled and Unbound will be discontinued in the future. Right?

Ashley•12/23/23, 10:27 AM

There’s nothing stopping you from using WebSockets with a Worker, you just can’t hibernate them like you can a Durable Object, so you’ll be billed for as long as the Worker has an open websocket connection (using Standard Pricing, for example)

Ashley•12/23/23, 10:27 AM

FWIW the paid plan is only $5/month, so incredibly good value and a low barrier to entry

Ashley•12/23/23, 10:53 AM

Ah I see, yes sorry you’ll need Durable Objects for that type of coordination - should let my coffee sink in before replying!

Ashley•12/23/23, 10:55 AM

I guess technically you could use D1, store state in there and have each Worker poll for state change but it’s getting real dicey now esp. considering DO’s keep it much simpler

Hi,

I would like to send mail from workers via SES?
But its sdk client is kind of Nodejs compatible lib.

Any suggestion?

You can try using fetch()fetch() to send a request to https://docs.aws.amazon.com/ses/latest/dg/send-email-api.html

Hey, I would like to create an API that multiple people can use. People should be able to easily create a token and use it. This token should be linked to their "account". I first tried to do this with unkey, but the cost is too high for me because I think I need a fair amount of "verifications". I recently ran into the hono framework and plan to use it. What do you guys recommend to me?

Gagan Suie•12/26/23, 8:14 AM

Adding itty-router-openapi caused issues with jest tests in Cloudflare workers.

Cyb3r-Jak3•12/26/23, 4:55 PM

Better would probably be #general-help if you are using a private ip address then you need to make sure the record isn’t going to be proxied or it will throw errors

Stefano•12/26/23, 11:32 PM

Is there a way to interpolate variable names in .dev.vars.dev.vars?

Something like:

VAR_NAME=$VAR_NAME_FROM_SHELL_ENV

VAR_NAME=$VAR_NAME_FROM_SHELL_ENV

Stefano•12/26/23, 11:33 PM

Apparently, .dev.vars.dev.vars is similar to dotenv. And this is possible in dotenv, but haven't been able to make it work in Wrangler.

kian•12/26/23, 11:41 PM

It just uses dotenv.parse to load them

Stefano•12/27/23, 12:14 AM

Ah. @kian Thanks for the heads up.

kian•12/27/23, 12:14 AM

I think the expansion stuff is from the add-on package, dotenv-expand, so not available in Wrangler

Unsmart•12/27/23, 4:11 PM

Millions per second for workers. You can use the cache api if you want. You can also use public buckets to add your domain instead of using a worker.

Unsmart•12/27/23, 4:13 PM

R2 can handle a few thousand rps (like 15-20k iirc). But cache can push that further since it won’t hit R2
