DNS Seeds

DNS seeds are one of the methods used to find initial peers for Litecoin Core and SPV wallets like Litewallet.

Mainnet:

src/chainparams.cpp
seed-a.litecoin.loshan.co.uk
dnsseed.thrasher.io
dnsseed.litecointools.com
dnsseed.litecoinpool.org

Testnet v4:

src/chainparams.cpp
seed-b.litecoin.loshan.co.uk
dnsseed-testnet.thrasher.io
testnet-seed.litecointools.com

Seeding is provided by the litecoin-seeder, which crawls for available Litecoin Nodes and exposes a list of reliable nodes via a built-in DNS server. The litecoin-seeder can also filter via services provided by a node, such as NODE_WITNESS (0x8) or NODE_MWEB (0x1000000).

Querying can be done via a nslookup. Example provided below:

$ nslookup dnsseed.thrasher.io
