域名抢注包括三部分：列出即将释放的域名列表；查询何时释放成为可注册状态；下单注册。手工抢注模式早已是传说，现在您需要抢注服务的帮助才能抢注到目标域名。
怎样即将释放的域名列表
我所知道的的提供即将删除/已经删除的域名列表资料的网站：
1. http://justdropped.com
2. http://dnmeter.com
您也可以下载GoDaddy提供的即将结束拍卖的域名列表：
网址：ftp://auctions@ftp.godaddy.com
查询何时释放成为可注册状态
抢注域名的前提是需要知道目标域名是否变更为可注册状态。你需要权限访问几乎是随时更新的WHOIS中心数据库（然而仅对注册商们开放权限），公开的WHOIS查询接口是有较大延迟的，不足为据。
你可以在Linux服务器上安装一个程序 jWhois ：
yum -y install jwhois
Jwhois 可以帮助你获得WHOIS的所有重要资料：创建日期、过期日期、域名服务器、注册商等等。你也可以使用它批量查询域名。请注意WHOIS服务器对每个IP的WHOIS查询次数的限制。比如 .ORG 的 WHOIS 查询限制是每分钟最多4次查询。
为了抢注到目标域名，你需要从返回资料中等到【not found】这样的信标字段。
然后你才能迅速向注册商提交注册请求。
这是一份ICANN所认证的注册商列表：

小的注册商不大可能和你竞争？不要让你的羊与狼共舞，不信试试看。
选择一个靠谱的域名抢注服务商
1. NameJet 和 SnapNames 是最大的2家域名抢注服务商。基本抢注价是 $69 ；如果有多人预订，那么会进入竞拍程序。
2. GoDaddy 也提供抢注服务。基本抢注价是 $20 ；如果有多人预订，那么会进入竞拍程序。
3. You can also find domain dropcatchers that don’t advertise by looking at who has registered a freshly dropped domain (check approximately an hour after the drop time). The best way to gauge the droptime is to note when Dynadot quits accepting bids on the dropping domain (about 15 minutes after that, the domain will drop). But some of these outfits look shady: BackorderZone / intrust domains / Bellnames / Dropwalk / Backorderzone.com are all owned by Epik and have been accused of being scam artists, so buyer beware. (They charge $49 per backorder, fyi).
4. Dynadot itself is actually one of the cheapest registrars at which to place a backorder. It costs about $17 to get a domain, but the success rate is low when compared to NameJet / SnapNames / Pool.
使用软件来抢注域名
Snatcher II is currently shut down, with a new version out in 2013 (under the name Snatcher 3, SiteSnatcher or DropKit). Product description from a user:
Snatcher is a drop catching software that can catch domains in “PENDING DELETE” status. It’s best to review the daily pending delete lists and find a domain you want. Then I would check Namejet or Snapnames to see if there are a bunch of bidders. If there isn’t then you stand a chance to grab it via Snatcher and register it through Dynadot (about $10 vs $59-69 to grab it via NameJet).
Every day (including weekends) .net/.com domains drop at 2 PM EST while .org domains drop at 9:30 AM. So normally I’ll sort through the lists and find one or possibly two I want to try to grab. Then set Snatcher to AUTO run when they begin to drop. The domains will drop (what seems to be randomly) beginning at 2 PM EST (for .net/.com). This sometimes takes 45 minutes before your domain will actually drop.
Software support has not been good. Update: he’s selling his entire business on Flippa.
