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.
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：
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.
