    How to set dns BIND server in a home machine


    Hello,

    I need my own DNS server in home machine. I have a DSL connection with dynamic ip address. I have installed ddclient, but nothing has changed. Is it possible to have DNS server with dynamic ip?

    Thanks.
    Alex.

    I run a small crawling software, which downloads content of a few urls. For this to work properly I need my own DNS server, since DNS of ISP provider cannot handle multiple requests and returns unknown Host error.

    Thanks.
    Alex.

    Hmm, this must be quite a lot of queries to either DOS the providers dns or run into some rate limit.
    Or the queries are wrong.


    Anyway, you probably want a caching only bind.
    Assuming your software runs within your private net, you can also run your own dns in there.
    The DNServer doesnt necessarily need to have a public IP in this setup, but the providerīs dns needs to be reachable by your own.

    The machines in your network will ask your dns.
    If your dns doesnt know the answer, it will forward the request to the provider dns.
    The answer is then cached and given to your machines.
    A new request for the same resource will then be answered from cache unless the TimeToLive has been exceeded.
