Hi there

I'm attempting to run BIND at home for a domain name I have established and wanting to run a DNS for.

I'm on a Fibre Gigatown Broadband & Landline plan and have a static IP

Just wanting to know/confirm

1) is port 53 blocked by Spark

2) how to get this block removed so I can run the service I want to

Thanks guys

Best, Paul

Hope your looking at configuring bind correctly so it doesn't act as a reflector or anything like that.

1. port 53 is blocked by default as is port 25 like any logical RSP.

2. spark.co.nz/port25 - both 25 and 53 open up here last i checked. (i'm still not convinced you actually want 53 opened.)

Any comments made are personal opinion and do not reflect directly on the position my current or past employers may have.

Thanks for the reply.

1. cheers I thought as much

2. that form does not state 53 only 25 and 25 I do not need open so if I use it, is the form an all or nothing option or is there a way to request 53 only?

Re BIND: Yep I am learning and certainly want to set something up that will not cause problems. I have a domain name that I recently acquired. My hope to offer members of a Fido Technical Network that I run a means to use the DNS service to offer each node a resolvable address based on their membership of the network and their node address.

Do the port 25 unblock request. The 53 is in the same policy as the 25. You're the first person I am aware of that wants 53 opened on a residential BB connection.

There's no way to request port 53 only.

I thought Port 53 was blocked as a DDOS protection?

thus my warning about configuring it correctly...

we do open it up though when asked.

As neil has stated, it's seldom to have a request like that.

OK thanks Neil I will complete the form and submit the request.

Yep, it wouldn't be a geekzone forum without a request from a nerd to do stuff the average punter would go "huh?" when asked. :)

In my case I'm enjoying mastering BIND and understanding DNS at a more detailed level.

Appreciate the help/info :)
