作者：zhanhailiang 日期：2014-11-01 1. host host提供域名到IP地址的双向解析； host默认通过/etc/resolv.conf读取Name Server来解析，除非提供可选參数server。 -a參数相当于进行ANY查询。 [root@~]# host pic1.vip.com pic1.vip.com is an alias for pic1.vip.com.wscdns.com. pic1.vip.com.wscdns.com is an alias for vipshop.xdwscache.glb0.lxdns.com. vipshop.xdwscache.glb0.lxdns.com has address 111.206.217.105 vipshop.xdwscache.glb0.lxdns.com has address 125.39.1.138 vipshop.xdwscache.glb0.lxdns.com has address 218.59.186.76 vipshop.xdwscache.glb0.lxdns.com has address 111.206.169.23 [root@~]# host pic1.vip.com 8.8.8.8 Using domain server: Name: 8.8.8.8

What is the maximum length of an IDNA converted domain name?

由 大兔子大兔子 提交于 2019-12-21 04:12:06
问题 First things first: I'm storing multiple domains to a database, after I've converted each and every domain name to it's IDNA version. What I need to know the maximum length such an IDNA-converted domain name can have so I can define the database field's max length. Known fact: Now, I know the maximum number of characters in a domain name (including any subdomains) is 255 characters. Where I lost it: That's easy at first glance, but... does this mean regular ascii characters of international

Docker container can reach DNS but not resolve hosts

由 亡梦爱人 提交于 2019-12-21 03:19:21
问题 I'm having an interesting problem running docker containers: out of the blue, I'm not able to resolve DNS from within the container. Here's a rundown: Nothing is resolving; apt-get, pip, one-off ping containers, etc. Running docker run -it --dns=8.8.8.8 ubuntu ping www.google.com results in ping: unknown host www.google.com both with and without the --dns flag. I can reach 8.8.8.8 both from inside and outside the containers. docker run -it ubuntu ping 8.8.8.8 works. I've configured the

How to restrict visibility of domain properties in grails?

由 随声附和 提交于 2019-12-21 03:15:14

wildcard in hosts file

由 情到浓时终转凉″ 提交于 2019-12-21 03:03:12
问题 It's not possible to use a wildcard in the hosts file on windows or linux. Is there a way to do it with a browser plugin or something else? I have a dev server on a vbox instance so it's practically LAN. I'm creating .dev domain for my virtual hosts so example.com becomes example.dev. For an application I'm creating random subdomains (abd34dn.example.dev) which should all point to the dev server's IP. What are my options? 回答1: Instead of editing hosts file (which does not work for your

Domain name classification API

由 拈花ヽ惹草 提交于 2019-12-21 00:26:07
问题 I need to categorize domains into different categories that offer the best use of a domain name. Like categorizing 'gamez.com' as a gaming portal. Is there any service that offers classification of domain name like Sedo is doing? 回答1: All the systems that I am aware of manage a list, somewhat by hand. Using a web-filtering proxies (e.g. WebSense) for inspiration, you could scan for keywords contained in the domain name, or in web content/meta tags at the specified location. However, there are
