Please explain what you mean by "all traffic" (SMTP? SNMP? HTTP? RPC?). What kind of redirect? DNS-level, HTTP-level, network-level? – milli Mar 26 '14 at 17:09
I meant HTTP traffic. Sorry I should have been more specific. – vibez_well Mar 28 '14 at 14:21

Domains don't deal with "traffic", they're just pointing out the IP address to contact a server. You can obviously set a different IP adress for topdomain.tld and In your case you even want to alias to, with a CNAME for exemple. You can then add a DNS A/AAAA record for and DNS zone will look like something like this: CNAME A A

The short answer, for HTTP, is No. and can have either the same A record or different A records in DNS. The web server you land on by using has to have rules that rewrite the URI to be and send a 301 Moved Permanently redirect response. This will cause the name to change in the browser and reload the new site.

This has no effect on domain names like which can be added with their own A records or even a CNAME.

Note: For real domain names called and, those are second-level registrations thus you cannot use a CNAME for those as they are by definition zone apex domains which have SOA and NS records attached. CNAMEs are illegal with any other record types.
