Access to the request IP #10

Closed brandonhilkert closed 5 years ago

brandonhilkert commented 5 years ago

Hey thanks so much for these gems! I assumed I'd have to deal with another language to put up a service like this.

We're looking to do a filter service based on request IP. With a downloaded ruleset from our services, look up the rules for that request IP, determine if it should be allowed, if allowed passthrough to a forwarding bind server, if not, serve backed an IP for a blocked page.

Two questions:

  1. Is there an easy way to access the request IP? I was having trouble following the sequence of the request in to the transaction.
  2. There are a lot of examples in rubydns, do you recommend using this dependency to build something like the above, or using rubydns as a starting point? The rules in rubydns didn't seem to match our requirements.

Ah, my bad, just found it in the options attr of the transaction. Thanks again!

I'd still be interested in your thoughts on 2 :)

RubyDNS was originally the entire stack. It split into async + async-dns + rubydns. RubyDNS is old, and it only really exists for compatibility or when you have a specific need for a DSL.

So, for 2, I'd suggest just building directly on top of async-dns.

Also, if you are building a commercial project and it's successful, please consider supporting the continued maintenance and development of async and async-dns :)
