从根域名服务器查到顶级域名服务器的NS记录和A记录(IP地址);
从顶级域名服务器查到次级域名服务器的NS记录和A记录(IP地址);
从次级域名服务器查出主机名的IP地址。
A记录: 将域名指向一个IPv4地址(例如:94.1.122.10),需要增加A记录;
CNAME记录: 如果将域名指向一个域名,实现与被指向域名相同的访问效果,需要增加CNAME记录。这个域名一般是主机服务商提供的一个域名;
MX记录: 建立电子邮箱服务,将指向邮件服务器地址,需要设置MX记录。建立邮箱时,一般会根据邮箱服务商提供的MX记录填写此记录;
NS记录: 域名解析服务器记录,如果要将子域名指定某个域名服务器来解析,需要设置NS记录;
TXT记录: 可任意填写,可为空。一般做一些验证记录时会使用此项,如:做SPF(反垃圾邮件)记录;
AAAA记录: 将主机名(或域名)指向一个IPv6地址,需要添加AAAA记录;
SRV记录: 添加服务记录服务器服务记录时会添加此项,SRV记录了哪台计算机提供了哪个服务。格式为:服务的名字.协议的类型;
SOA记录: SOA叫做起始授权机构记录,NS用于标识多台域名解析服务器,SOA记录用于在众多NS记录中那一台是主服务器;
PTR记录: PTR记录是A记录的逆向记录,又称做IP反查记录或指针记录,负责将IP反向解析为域名。

如何薅羊毛?
If you had 15 or more followers on github during the week of 2019-02-04, your github SSH & PGP keys are included in the merkle tree.
Likewise, roughly 30,000 keys from the PGP WOT Strongset have also been included in the tree.
As a final addition, Hacker News accounts which are linked with Keybase accounts are included in the tree provided they were ~1.5 years old during the crawl.
This merkle tree is computed and its root is added to consensus rules of the Handshake blockchain, allowing the owner of a key to publish a signed merkle proof on-chain in order to redeem their airdrop.
With the final mainnet key list, every open source developer will receive 4,246.994314 HNS coins from the airdrop.
安装git 能够访问外网,例如 Google nodejs > >= 8.0.0 github 有绑定ssh公钥 GitHub帐户的有添加 SSH密钥 Node.js> = 8.0.0 拥有钱包地址,在 https://www.namebase.io/airdrop 注册即可获得 (需要能访问外网)
<path to key >是你本地可以访问GitHub 账号的ssh密钥; <address>是你的钱包地址,在https://www.namebase.io/airdrop 查看文档获取;
