The above is node data of IPv4.
These are converted to 16 bits IPv6 and placed in chainparamsseeds.h
what these are means and how use?
also, chainparams.cpp
vSeeds.push_back(CDNSSeedData("loshan.co.uk", "seed-a.litecoin.loshan.co.uk", true));
vSeeds.push_back(CDNSSeedData("thrasher.io", "dnsseed.thrasher.io", true));
vSeeds.push_back(CDNSSeedData("litecointools.com", "dnsseed.litecointools.com"));
vSeeds.push_back(CDNSSeedData("litecoinpool.org", "dnsseed.litecoinpool.org"));
vSeeds.push_back(CDNSSeedData("koin-project.com", "dnsseed.koin-project.com"));
What's the difference with these above?
The domains listed in chainparams.cpp are for DNS seeders. DNS seeders are not nodes themselves, but rather are DNS servers that serve the IP addresses of nodes that are available to be connected to. These can be connected to for both a normal connection and just one to retrieve more IP addresses of nodes.
The IP addresses listed in chainparamseeds.h are the IP addresses of nodes that can be connected to. This connection can be an actual connection or just one which retrieves more IP addresses of nodes that can be connected to.
To setup a seed node, you just need to run a normal node for your altcoin and add its IP address to chainparamseeds.h. There should be a script that actually constructs this for you in contrib/seeds.
