check if an IP is within a range of CIDR in Python

问题 I know there are some similar questions up here, but they mostly either want to find the range itself (which uses some libraries, like the example that stackoverflow says is a dupe of my question) and is in another language. I have a way to convert the subnet into the beginning and the end of the range of ip's in a subnet (okay, bad wording, it's simply like 1.1.1.1/16 -> (1.1.0.0 , 1.1.255.255) ) I now want to check if 1.1.2.2 is within this subnet. Can I simply do a > and < to compare? ip

Postgress | SQL | Get a row only if the subnet is part of a given ip list

问题 I have a table with text column that holds ip with subnet | ip ------------- | 1.1.1.1/30 when you convert 1.1.1.1/30 to list of ip you get: 1.1.1.0 1.1.1.1 1.1.1.2 1.1.1.3 I want to run a sql on this table and give a list of ips somehow as part of "where" or anything else, and get this row only if the list of the ips that I give contain the ips of the range in the row. meaning, where ('1.1.1.0','1.1.1.1) --> I will not get the row but: where ('1.1.1.0','1.1.1.1,1.1.1.2,1.1.1.3) --> I will

Facebook scraper uses incorrect DNS data > my site is not gettng scraped

问题 I recently moved one of my sites (gezondbenjij.nl) to a new hosting account. This resulted in a new IP address. Unfortunately, since the move, the Facebook scraper cannot find my site on the new IP address. It still uses the old IP. All DNS settings are correct, and every browser/client/tool finds the correct site at 178.22.57.204 (gezondbenjij.nl). Except for Facebook.. The facebook scraper lands in my old hosting account. So I guess their hostfile or DNS cache still holds the old data. Even

How to perform a ping-test programmatically on Windows?

早过忘川 提交于 2020-07-22 07:52:13
问题 I'd like to make an IP-test in a C command line program on Windows . Now I'm using the cmd-command in my program with something like this: if(system("ping -c1 8.8.8.8 -w 2 ") == 0){ printf("request successful\n"); return true; }else{ printf("request not successful\n"); return false; } Please note that the code above is just an example: with my program I will try to ping some devices, to see if they are online; if not I know there is a connection issue. Since I need only the connection status

Check if IP address is in private network space

邮差的信 提交于 2020-07-17 10:48:01
问题 I have a program in go which accepts URLs from clients and gets them using the net/http package. Before doing further processing, I would like to check if the URL maps to private (non-routable / RFC1918 networks) address space. The straight-forward way would be to perform an explicit DNS request and check the address for the known private ranges. After that, perform the HTTP GET request for the URL. Is there a better way to accomplish this? Preferably integrating with http.Client so it can be
