Example of usage of Dns class

Resolve domain name

Tonlib tonlib = Tonlib.builder().build();
Dns dns = Dns.builder()
        .tonlib(tonlib)
        .build();
Address rootAddress = dns.getRootDnsAddress();
log.info("root DNS address = {}", rootAddress.toString(true, true, true));

Object result = dns.resolve("apple.ton", DNS_CATEGORY_NEXT_RESOLVER, true);
assertThat(result).isNotNull();
log.info("apple.ton resolved to {}", ((Address) result).toString(true, true, true));

Address addr = (Address) dns.getWalletAddress("foundation.ton");
log.info("foundation.ton resolved to {}", addr.toString(true, true, true));
assertThat(addr).isNotNull();

Deploy DNS collection

WalletV3R1 adminWallet = GenerateWallet.randomV3R1(tonlib, 20);

log.info("admin wallet address {}", adminWallet.getAddress());
