Use location.host and cut off subdomains and the TLD: var domain = (location.host.match(/([^.]+)\.\w{2,3}(?:\.\w{2})?$/) || [])[1] update: as @demix pointed out, this fails for 2 and 3-letter domains. It also won’t work for domains like aero, jobs and dozens others. The only way around is to know valid TLDs in advance, so here is a more … Read more
There are 2 steps you need to perform, Add the custom domains addon and add the domain your going to use, eg www.mywebsite.example to your application Go to your domain registrar control panel and set www.mywebsite.example to be a CNAME entry to yourapp.herokuapp.com assuming you are using the CEDAR stack. There is a third step … Read more
The hint (using axfr) only works if the NS you’re querying (ns1.foo.example in your example) is configured to allow AXFR requests from the IP you’re using; this is unlikely, unless your IP is configured as a secondary for the domain in question. Basically, there’s no easy way to do it if you’re not allowed to … Read more
This may occur if a hiccup in DNS server has occurred. Apart from making the DNS server more robust or looking for another one, you can also just use the full IP address instead of the hostname. This way it doesn’t need to lookup the IP address based on the hostname. However, I would rather … Read more
DNS cannot redirect your www site to non-www. The only purpose of DNS is to point both www and non-www to your server’s IP address using A, AAAA or CNAME records (it makes little difference). The nginx configuration is responsible for performing the redirect from www to non-www. Your second server block is intended to … Read more
I finally dug up the obscure command from MSDN that fixes this: ServicePointManager.DnsRefreshTimeout = 0; As I unwound all the weird things I’d tried previously, I discovered one other setting that I need along with the one above; on the request object, turn off keep-alive: request.KeepAlive = false;
Your code retrieves the address as a “socket address” structure. getnameinfo() can be used to convert the address into a numerical IP string (code recycled from https://stackoverflow.com/a/25627545/1187415, now updated to Swift 2): let host = CFHostCreateWithName(nil,”www.google.com”).takeRetainedValue() CFHostStartInfoResolution(host, .Addresses, nil) var success: DarwinBoolean = false if let addresses = CFHostGetAddressing(host, &success)?.takeUnretainedValue() as NSArray?, let theAddress = … Read more
var parts = location.hostname.split(‘.’); var subdomain = parts.shift(); var upperleveldomain = parts.join(‘.’); To get only the second-level-domain, you might use var parts = location.hostname.split(‘.’); var sndleveldomain = parts.slice(-2).join(‘.’);
This should work: //this gets the ip address of the server pc public string GetIPAddress() { IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName()); // `Dns.Resolve()` method is deprecated. IPAddress ipAddress = ipHostInfo.AddressList[0]; return ipAddress.ToString(); } http://wec-library.blogspot.com/2008/03/gets-ip-address-of-server-pc-using-c.html OR //while this gets the ip address of the visitor making the call HttpContext.Current.Request.UserHostAddress; http://www.geekpedia.com/KB32_How-do-I-get-the-visitors-IP-address.html
Here’s my idea, Match anything that isn’t a dot, three times, from the end of the line using the $ anchor. The last match from the end of the string should be optional to allow for .com.au or .co.nz type of domains. Both the last and second last matches will only match 2-3 characters, so … Read more
