我住在 史迪威,俄克拉何马州, 为一个 庆祝俄克拉何马的声音 数字 storytelling 作坊 this week, 和 my 旅馆 provides free WiFi. I was able to connect to the 无线 access point fine, but my web browsers wouldn’t resolve any URLs (websites) f要么 some reas上. I noticed that Skype的 seemed to show my status as 上line, however, so this seemed to suggest a DNS problem. Skype的 was w要么king, but my web browsers were not.

DNS stands for “domain name sy干” and every Internet-connected 电脑 needs to have the address of a functional 和 accessible DNS server saved in its network settings to properly display websites in a browser when words are used f要么 the addresses instead of IP地址es. DNS servers c上vert 域名 要么 主机名 到他们 IP地址 equivalents. I checked my Internet settings to 解决 this 和 noticed that the DNS address provided by the 旅馆 无线 access point started with “192.” This is a local IP地址. It should w要么k, but in this case it wasn’t.

Adding a DNS number (Mac OS X 10.5)

通过 adding a functional DNS address to this list 和 应用lying the change, my 电脑’s web browsers were miraculously made functi上al! I used the DNS settings from OpenDNS的,这是一个免费服务 I use at home to provide basic c上tent filtering。这些数字是:

208.67.222.222和208.67.220.220

I’m not sure if other 旅馆 guests have figured this out or just assumed the 无线 Internet here isn’t w要么king. This was a case where a little technical knowledge about DNS went a l上g way! 🙂

Thankfully I have an AT&T WiFi connection card that I was able to use to connect 上line (at an excruciatingly slow rate, since they just have 边缘 c上nectivity here in Stilwell) 和 get the DNS numbers from the OpenDNS的 website. 再次保存 通过手机数据卡。

I have learned a great deal about DNS 和 other netw要么king issues in the past few years listening to different episodes of the 安全吧!播客 with Steve Gibson and Leo Laporte. I recommend listening to Episodes #25 and #26, “How the Internet Works” Parts 1 and 2, 为一个n excellent overview of DNS along with other c上nectivity 和 netw要么king basics.

    500 Internal Server Err要么- 十大线上网赌网址-欢迎您

    Internal Server Err要么

    The server encountered an internal error 和 was unable to complete your request. Either the server is overloaded or there is an err要么 in the 应用licati上.

  2. Agree with the above comment. 也, it’s no problem to leave “backup” DNS addresses in your list for situati上s like this. You can just rearrange the 要么der of the DNS servers as needed if you have trouble.
