Is there support for using ingress-nginx in kubernetes?

Also is there a list of supported servers/software? I clicked on a few links from the home page and they took me to a page asking for an e-mail to be notified when they're available in the future.

Does the free plan even allow blocking anything? All the Pricing page says is "IP Investigation" for the free/oss plan, leading me to assume most features are behind a paywall?
