ip-address

问题 I have regular expression like match = re.findall(r'[0-9]+(?:\.[0-9]+){3}', source) It works fine to take something like 192.168.1.1 from source string. How I can modify this regular expression for make it work with something like this: 192.168.1.1:80 Thank You for help. P.S. Sorry for my bad english. 回答1: This will match IP addresses with ports numbers. match = re.findall(r'[0-9]+(?:\.[0-9]+){3}:[0-9]+', source) If you want to make it flexible to match IP address without the ports and With

问题 I have a question regarding IP Address in Google App Engine . I know there is no way to have a static IP-address, but my client have setup a Custom Domain with some IP-address showing up. My problem is: There is an endpoint(API) that they are connected on, the problem is that the destination requires IP-address and PORT to open in their firewall-policy. Since there is no "Static IP" on Google App Engine, can i use those IP-address showing under "data" in Google App Engine in Custom Domains ?

问题 I have an unusual problem. I am running a simple node.js app. The code below works. var app = require('http').createServer(handler); var io = require('socket.io').listen(app); app.listen(8000, '127.0.0.1'); However, if I use app.listen(8000, '192.168.1.4'); , no client is able to connect to the server. 192.168.1.4 is the IP address of my local machine. One thing I noticed is that even when app.listen(8000, '127.0.0.1'); is used, on the local browser, http://localhost:8000/ works but http:/

问题 I'm trying to generate a random IP address given a subnet of IP address. There are plenty of resources available to generate a random IP, but my requirement it to have it generated from within a specific subnet. I've used an npm module called netmask - however the implementation is absolutely not elegant. Can anyone please give some slick pointers to this? var netmask = require("netmask").Netmask var block = new netmask('10.0.0.0/24') console.log(block) // gives block details var blockSize =

问题 I am trying to read a set of IPs from a text file and add it to a IPAddress type list. An exception is raised on the line "listIPAdrrs.Add(IPAddress.Parse(list[i]));" The exception is An invalid IP address was specified.

问题 I have a database server configured on AWS and I want to restrict access to it only from my computer's IP. The problem is as IP addresses get assigned dynamically by the ISPs, I manually need to whitelist my IP address before accessing the server from my computer, everytime I switch from my home network to some other network. I have been able to set a static IP address for my machine, but when I try to change my ISP from local broadband to mobile internet's hot-spot or to another network

问题 I don't understand what it means to bind a socket to any address other than 127.0.0.1 (or ::1, etc.). Am I not -- by definition -- binding the socket to a port on my own machine.. which is localhost? What sense does it make to bind or listen to another machine or IP address's port? Conceptually, it just doesn't make sense to me! (This has proven surprisingly hard to Google... possibly because I'm not Googling the right terms.) 回答1: Binding of a socket is done to address and port in order to
