2. Depending on what source you are using, these likely can just be IP Addresses.

They can't be IP addresses. The DNS seeders are not servers that you send queries to. Rather you do a DNS lookup for the domain name, and because the DNS seeder is configured to be the nameserver for that domain, it will provide DNS records that are for the domain. However those records don't point to any IP addresses for a server at that domain; rather they point to nodes that you can connect to.

Thanks for the clarification, I was not 100% sure.
You could always do an addnode with the actual IP address though - I've found that to be a useful way of testing nodes with altcoins.

1. Any site that provides hosting - you can even provide a seednode on your home PC if you wanted to.

2. Depending on what source you are using, these likely can just be IP Addresses.

Below is a snippet from src/chainparams.cpp for Bitcoin - note that these are again URLs but URLs are pointing to IP Addresses

Code:

// Note that of those which support the service bits prefix, most only support a subset of
// possible options.
// This is fine at runtime as we'll fall back to using them as a oneshot if they don't support the
// service bits we want, but we should get them updated to support all service bits wanted by any
// release ASAP to avoid it where possible.
vSeeds.emplace_back("seed.bitcoin.sipa.be"); // Pieter Wuille, only supports x1, x5, x9, and xd
vSeeds.emplace_back("dnsseed.bluematt.me"); // Matt Corallo, only supports x9
vSeeds.emplace_back("dnsseed.bitcoin.dashjr.org"); // Luke Dashjr
vSeeds.emplace_back("seed.bitcoinstats.com"); // Christian Decker, supports x1 - xf
vSeeds.emplace_back("seed.bitcoin.jonasschnelli.ch"); // Jonas Schnelli, only supports x1, x5, x9, and xd
vSeeds.emplace_back("seed.btc.petertodd.org"); // Peter Todd, only supports x1, x5, x9, and xd

Hello!

I have a two questions:

1. Can you recomend me anonimous hosting where I can placed a seed-node for altcoin?

2. In src/net.cpp on BC 0.8:

Code:

// DNS seeds
// Each pair gives a source name and a seed name.
// The first name is used as information source for addrman.
// The second name should resolve to a list of seed addresses.
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}
};

A first name - is anything I want?

or necessarily real domain name binded with?

A second name - may be an IP?

Thank you.
