More than two serving IPs
Hello Workers friends,
I know this is a bit ridiculous to ask since connection pooling isn't optimal on HTTP/2, but we have a large share of HTTP/1.1 traffic that we can't control, and it happens to spread by available number of IPs. On Workers, we only have two; elsewhere, we can assign multiple.
We could, in theory, proxy in front of Workers, but obviously that defeats the benefits of Cloudflare's amazing network footprint and routing. Is there a way to get more than two serving IPs on a Worker, without proxying? Thank you so much for any help.

So while workers only show 2 IPs Cloudflare uses anycast so those IPs are shared by locations around the global which will split up your traffic
?anycast
Take a look here to see why the Cloudflare datacenter you are routed towards isn't always the closest geographically: https://community.cloudflare.com/t/peering-why-dont-i-reach-the-closest-datacenter-to-me/76479

Peering - Why don't I reach the closest datacenter to me?
Why don’t I reach the closest datacenter to me? Cloudflare is an anycast network, so where you are routed is determined by peering with ISPs. The shortest path geographically isn’t always possible due to peering agreements.

@Cyb3r-Jok3 thank you, that is correct, but the client side of this traffic pools connections (HTTP/1.1) based on the number of IP addresses returned. We're not at all worried that Cloudflare can handle the load over two IPs, and we know those two IPs represent thousands of hosts.
Hey @flpydsk thank you, but wouldn't that route our traffic to nginx?
We are an Ent customer so that may be our saving grace. I'll speak to them. Additionally, I don't think we could map the IPs manually because they will change, right? So we'd be guaranteeing an outage if we did that
Yeah reach out to your CSM about this. They might know ways around it
Thank you @Cyb3r-Jok3 i'll give that a try
