A simple question. Is there a generic term for hostname and IP address? I would like to call them in with one name in a UI field.
You can use term like Server Address or Destination Server, if that helps.

I am now just starting to understand Httpcontexts and server side logic. Total beginner.
I have understood how to read the http requests from a client and get the remote IP etc.
I came across the hostname property.
I believe hostname and domain are completely different.
My undersanding is that stackoverflow is the domain name.
Given its widespread reach, stackoverflow can have multiple servers and hence multiple ip addresses.
So is there a way to determine to which server a client is requesting to in asp.net core 2.0?
You are correct that stackoverflow.com is a domain name. A domain name points to an IP address. That's called DNS. stackoverflow.com points to one single IP address not multiple. There's probably a load balancer at that IP address which then points you to an available server, which is internal you can't see that, but that's another story.
If you ping stackoverflow.com you get:
The whole point of DNS is to not use IP address but a domain name.
I'm not sure why you would want to see the IP. Maybe this stackoverflow question can help: Resolve HostName to IP
In my local network exists pcs, where have a hostname as example "testhost". How can I from given hostname get a IP-address ?
I tried:
net_adm:dns_hostname("testhost.fritz.box").
Result:
{ok,"testhost.fritz.box"}
I need a function which give me IP-Address from hostname.
Thx
According to http://erlang.org/doc/man/inet.html#getaddr-2 it seems you should be able to use getaddr like:
inet:getaddr("testhost.fritz.box", inet)
I have a structure which unites IP address and port number. What's a proper name for such a thing?
According to Wikipedia, it's called a socket address.
The .NET framework calls it an IPEndPoint.
Apologizes if this is readily available somewhere but I'm not able to find it on google easily.
I'm wondering if an IP address will always have a corresponding domain name/URL. We are looking to remove acceptance of IP addresses and require our clients to pass a domain name instead but wanted to ensure that this is possible.
The answer is No.
An IP with a corresponding domain name/URL is strictly for readability purposes. You can map a particular IP to a domain name using a DNS server but it is entirely optional.

All,
I have an IP address and I want to know all aliases within my organization that point to this IP. Is it possible?
For example I know the alias "TESTBOX" points to 119.119.119.119.
How can by just knowing the IP come up with the "TESTBOX" ?
Thanks,
M
Short answer: You can't.
You can try a reverse lookup on the IP address, but that will only show you the address that has been specifically allocated in the reverse DNS to that IP address.
Remember, aliases might exist only as an entry on a single machine's hosts file. They might also exist in a DNS server on the other side of the planet. However, if you're only interested in local DNS aliases, and your DNS servers allow zone transfers, then you can try listing every entry in every domain (eg. with host -l xyzzy.bigcorp.com) and searching the results for the IP address in question.
