找到了,只怕是原来的两个 DNS 不能用。
/etc/resolv.conf
As noted above, this is the file you use to enter your DNS server information. Unless you have your own Internet DNS server, this file will contain information about your ISP.
search yourisp.com
nameserver 172.25.188.66
nameserver 172.25.188.77
Your ISP's domain and DNS server IP addresses would be entered in place of the blue entries above.
What about having your own Internet DNS server? Bad idea. First of all, when you register a domain name with someone like Network Solutions you're required to enter the IP addresses for two DNS servers. This is because DNS is critical. If it fails no one will be able to "find" (get the IP address of) your Web, e-mail, or other Internet servers. Thats why a proper DNS server setup includes two servers with two different addresses (for redundancy). And since an ISP will typically only allocate a few static IP addresses to you, using two of them just for DNS isn't very efficient. If you need DNS records for an Internet Web or e-mail server, check with your ISP. They will usually host your DNS records on their DNS servers for a small one-time setup fee ($5 in the case of our ISP). |
