Are you connecting to the client org network via VPN? "Connectra" appears to be a Check Point IPSec VPN. While connected, some VPN servers can be configured:

- to give your computer an IPv4 address on the customer's LAN. That will usually be a private address i.e. https://www.arin.net/reference/research/statistics/address_filters/ . The address you X'd out above should be in one of those ranges. But, if it is private, Google public DNS (8.8.8.8) should not be able to resolve it. If your default nslookup server is Google Public the address returned may be your customer's external (WAN) IPv4 address

- to append a domain name of their choice to your computer's host name so it can be resolved on the customer's local network. That could be why you're seeing "dell2018.ClientOrganizationName.org" as an alias

If that's what's happening, you need to disconnect from the VPN before you try connecting to your local web server using http://dell2018:8080/test.aspx .

If the VPN has so-called split DNS configured, that can complicate things even further.
