Title: How to set up new DNS Seeds for an altcoin?
Post by: shamoons on October 30, 2013, 06:57:54 PM

I noticed that in the bitcoin source code, we have:

Code:

static const char *strMainNetDNSSeed[][2] = {
    {"bitcoin.sipa.be", "seed.bitcoin.sipa.be"},
    {"bluematt.me", "dnsseed.bluematt.me"},
    {"dashjr.org", "dnsseed.bitcoin.dashjr.org"},
    {"xf2.org", "bitseed.xf2.org"},
    {NULL, NULL}
};

If I'm creating my own altcoin, I should probably start by changing these seed nodes. When setting up a new node, how exactly will it return data? Are these the domains that point to bitcoin clients currently running and from that, the process of peer discovery can grow?

Sorry, I got no answer for you cause I'm looking for the same information. Hope someone of this community is willing to share his knowledge? ;)

Someone told me once upon a time that seeds are not nodes but, rather, hostnames / subdomains / domains whose DNS is on a modified DNS-server, one that has been modified to use the list of current live nodes to populate the hostname with currently live nodes.

So basically instead of merely plugging into your DNS a whole bunch of IP addresses that people have claimed they would maintain nodes at, your DNS server itself answers DNS queries with the IP address of nodes that actually are alive at the time and actually do have their incoming port open at the time.

That's a pretty slick little trick.

Does anyone know of a repo for anything like that?

But wouldn't it just be a lot easier to have a simple HTTP response with a text list of 1 IP per line?

Is there any real advantage to using a modified DNS server?

In case we're talking about a Litecoin clone (scrypt), I've read somewhere that mentioning DNS Seeds in the coding (in net.cpp) isn't necessary but I don't know if this statement is correct.

The main reason of having DNS seed server is to solve the "no connection" issue. The wallet(client) check-in to DNS seed server when it start up to 1. report to it as an active node & 2. get other active nodes available.

DNS seed is optional for most crypto currencies, but for a new alt coin, better to have it as it helps a lot with connection issues.

It is NOT a node.
