create a domain name pointing to an IP of port different than 80
The domain company that you talked to may have done a poor job of explaining how domains work. Domain names don’t refer to specific ports. They just refer to IP addresses. The client can look up a hostname to get the IP address which the client should connect to, but the client has to figure out the port without the help of DNS. Port 80 is just the default port for HTTP service.
You can certainly run a web server on port 8088 if you like. The port number would have to appear in the URL, e. g.. Clients would parse this and know to connect to port 8080 instead of the default port 80.
If you don’t want URLs to contain the port number, then requests are going to go to the default port 80, and you have no choice but to make the web server running on port 80 handle these requests. HTTP/1. 1 requests include the hostname which the client wants to contact, and modern web server programs are normally capable of serving completely different sets of content based on the hostname in the request. There are few ways todo what you need:
Just configure the web server for port 80 to handle both sites. This will depend on what web server software you’re using. Apache for example calls these “virtual hosts”, and here is a set of examples. This is a typical solution, and some people run hundreds of sites on the same server this way.
Run your two web servers as you planned. Set up the server for port 80 to be a reverse proxy for the second website. The server would continue to serve content for the site it handles now. When it receives a request for the second site, it would relay the request to the server running on port 8088, and relay the server’s response back to the client.
Move the existing server for port 80 to a different port. Run a pure reverse proxy server on port 80, relaying requests for both web sites to their respective web servers.

How to find Port number of IP address? – Stack Overflow
We can find out IP address of a domain name or URL. But how to find out Port number on which a domain name is hosted?

Unfortunately the standard DNS A-record (domain name to IP address)
used by web-browsers to locate web-servers does not include a port
number. Web-browsers use the URL protocol prefix () to
determine the port number ( = 80, = 443, ftp = 21, etc. )
unless the port number is specifically typed in the URL (for example
” = port 5000).
Can I specify a TCP/IP port number for my web-server in DNS? (Other than the standard port 80)

Quite an old question, but might be helpful to somebody in need.
If you know the url,
1. open the chrome browser,
2. open developer tools in chrome,
3. Put the url in search bar and hit enter
4. look in network tab, you will see the ip and port both

DNS server usually have a standard of ports used. But if it’s different, you could try nmap and do a port scan like so:
> nmap 127. 0. 1

The port is usually fixed, for DNS it’s 53.

Port numbers are defined by convention. HTTP servers generally listen on port 80, ssh servers listen on 22. But there are no requirements that they do.

If it is a normal
then the port number is always 80
and may be written as Though you don’t need to specify it as:80 is the default of every web browser.
If the site chose to use something else then they are intending to hide from anything not sent by a “friendly” or linked to.
Those ones usually show with
and their port number is unknown and decided by their admin.
If you choose to runn a port scanner trying every number nn from say 10000 to 30000 in Then your isp or their antivirus will probably notice and disconnect you.

Use of the netstat -a command will give you a list of connections to your system/server where you are executing the command.
For example it will display as below, where 35070 is the port number
TCP 10. 144. 159:**52121** sd-s-fgh:35070 ESTABLISHED

Frequently Asked Questions about domain port
What is domain port?
Domain names don’t refer to specific ports. They just refer to IP addresses. The client can look up a hostname to get the IP address which the client should connect to, but the client has to figure out the port without the help of DNS. Port 80 is just the default port for HTTP service.Sep 29, 2017
How do I find my domain port?
Web-browsers use the URL protocol prefix (http://) to determine the port number (http = 80, https = 443, ftp = 21, etc.) unless the port number is specifically typed in the URL (for example “http://www.simpledns.com:5000” = port 5000).Oct 1, 2011
What is the 53 port?
DNS uses Port 53 which is nearly always open on systems, firewalls, and clients to transmit DNS queries. Rather than the more familiar Transmission Control Protocol (TCP) these queries use User Datagram Protocol (UDP) because of its low-latency, bandwidth and resource usage compared TCP-equivalent queries.Mar 15, 2019
