How to redirect a domain to another one on my machine only?

Question

I want all requests from my machine to

example.com

be redirected to

example.com.edgesuite.net

I tried adding the following line to the hosts file both on Windows and Linux

example.com.edgesuite.net        example.com

but the nslookup still resolves to the old IP.

Answer 1

The hosts file expects an IP address for each hostname listed.

You may need to look up the IP address of example.com.edgesuite.net and use it in the hosts file.

First perform the DNS lookup:

C:\>nslookup example.com.edgesuite.net
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
Name:    a1081.b.akamai.net
Addresses:  24.143.196.115, 24.143.196.123
Aliases:  example.com.edgesuite.net

Then add a line line in your hosts file such as:

24.143.196.115 example.com

or

24.143.196.123 example.com

But keep in mind that if example.com.edgesuite.net ever changes its IP address, then you will have to make a corresponding change in your hosts file.
