Find all domains under a TLD

阅读更多关于 Find all domains under a TLD

问题 I'm trying to find a way to list all registered domains under a top-level domain (TLD). I.e. everything under .com, .net, etc. All the tools I find only applies to finding subdomains under a domain. 回答1: The information you seek isn't openly available. However, there are a few options you can try: You might want to try inquiring at the respective registries directly about getting access to the Zone files. However, the process can take weeks and some registries choose not to offer access at

问题 I would like to know if is possible to get IPv4 and IPv6 address with just one command dig, and how? For example: dig hostname A - the command above will give the IPv4 dig hostname AAAA - and this command will give me the IPv6 address How can i get both addres, Ipv4 and IPv6, with just one command? I got stuck in this problem, how can i get IPv4 and IPv6 with a authoritarian query, but with just one command? Anyone can help me??? 回答1: If you're querying an authoritative server for the domain,

Yesterday I changed my domain's name server from cloudflare to dnspod. And I used dig to test it. But the ANSWER SECTION is always the old name servers. ;; AUTHORITY SECTION: amazingjxq.com. 21336 IN NS kim.ns.cloudflare.com. amazingjxq.com. 21336 IN NS brad.ns.cloudflare.com.

Safely assign value to nested hash using Hash#dig or Lonely operator(&.)

阅读更多关于 Safely assign value to nested hash using Hash#dig or Lonely operator(&.)

问题 h = { data: { user: { value: "John Doe" } } } To assign value to the nested hash, we can use h[:data][:user][:value] = "Bob" However if any part in the middle is missing, it will cause error. Something like h.dig(:data, :user, :value) = "Bob" won't work, since there's no Hash#dig= available yet. To safely assign value, we can do h.dig(:data, :user)&.[]=(:value, "Bob") # or equivalently h.dig(:data, :user)&.store(:value, "Bob") But is there better way to do that? 回答1: It's not without its

How to query authoritative name server to side-step propagation times?

阅读更多关于 How to query authoritative name server to side-step propagation times?

问题 I have a domain with 123-reg.co.uk and I've created a TXT record: I have tried to verify it has been applied by using both the dig and host shell commands, but it appears the TXT record isn't being found. For example... host -t txt integralist.co.uk ...returns: integralist.co.uk has no TXT record At first I assumed it might be a TTL issue and so I tried to use dig to query one of the authoritative name servers directly (thus avoiding a TTL caching concern), like so dig txt integralist.co.uk

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I must write a C/C++ program which works a little bit like dig and nslookup: it must know IP addresses of any site. It should do things like the dig www.example.com MX +short command does. I can't imagine how can

Detecting Handwritten Prime Digits with Neural Networks November 20, 2019 100 points 1 Introduction Prime numbers are fantastic. In this assignment we will use Multi Layer Perceptrons to detect handwritten prime digits. But before doing such a difficult task I suggest to try and solve an easier problem with MLP. If you succeed, which I know you will, you can proceed with tackling the challenging problem of detecting handwritten prime digits. 2 Regression - Toy Data The first task is to learn the function that generated the following data, using a simple neural network. The function that

0.展示PTA总分一维数组二维数组 1.本章学习总结 1.1 学习内容总结 1.数组中如何查找数据：可以用循环语句将数组中所有的数检查一遍，若找到便退出循环语句；还有二分法：定义left（数据集的开头），right（数据集结尾）两个变量，然后在这组数据中找到mid=(left+right)/2，然后将待查找元素与mid所指元素进行比较，如果相等将索引返回，如果查找元素大于mid所指元素，则将left向右移动即left=mid+1;如果查找元素小于mid所指元素，则将left向左移动即right=mid-1。重复以上过程直到left>right(因为此时表明并不存在待查找元素) 2.数组中如何插入数据：把数据放在需要的位置之后，该位置原本的数往下移一位 3.数组中如何删除数据：将该位数用下一位的数来代替，然后接下来的数也依次往前移动一位，也可以重新定义一个数组，重新存放除要删除的数据之外的所有数据。 4.数组中目前学到排序方法：冒泡排序法：用循环语句来对比每两个相邻的数据，大的数下沉，小的数上浮。选择排序法：每一次从待排序的数据元素中选出最小（或最大）的一个元素，存放在序列的起始位置，然后，再从剩余未排序元素中继续寻找最小（大）元素，然后放到已排序序列的末尾。以此类推，直到全部待排序的数据元素排完。 5：哈希数组：不懂 1.2 本章学习体会代码量：421 2.PTA实验作业 2
