no, nothing about DNS, it's only layer3 translation, explication inside:

Network Address Translation allows a single device, such as a router, to act as agent between the Internet (or ""public network"") and a local (or ""private"") network.

detail explication see the link.

beware, in an entreprise environment, people use PAT, it also called NAT overload, means every global addr in NAT pool can use up to 64000 connection(actually around 4000), it uses tcp/ip port map to an inside addr.

      • 家用的路由器好像就能log outgoing pakets
    • Those SOHO router is equiped with NAT and Firewall. You can set to block the particular TCP or UDP port if you know the application. But you can not do it to the web address. Try to use content control under explorer.
      • 什么是NAT?
        • Network Address Translation, why just google internet, you find all answer in five min???
          • it is similar to Reverse DNS( IP to domain name) ?

    • Router works in the network layer, web works in the application layer. You expect the network layer stuff to control/monitor app layer stuff?
      Not entirely impossible, but it'll be hard. Better use web proxy like squid ...
    • dennis, 你的英文很棒, 我感觉,尽管我的英文不好, 双丛的否定再加上entirely, NAT 用于network layer, 理解对吗?
      • 我怎么感觉象Chinglish?“不是完全不可能”。嘿嘿。
    • 取决于你的路由器,在SMC路由器的防火墙(firewall)里面可以用URL Blocking 跟 Schedule Rule 设置屏蔽某台机器在某个时候上某些网站
