Is SID allowed to show up in /etc/hosts file?

29 Views

Experts:

I am looking into a /etc/hosts which has something I never saw before.

Every entry in that /etc/hosts file has a format as follows:

123.23.456.678 CHERRY CHERRY.RIO.COM SID CHERRY.BRAVO.NET

For example:

123.23.456.678 CHERRY CHERRY.RIO.COM PRO CHERRY.BRAVO.NET

Observation:

0) WHY SID (here is PRD) gets into the hosts file? Would it cause some issues?

1) each entry has 2 aliases ;

2) "nslookup CHERRY.RIO.COM "

2a) will return the correct IP address IF I run this nslookup on the server

2b) will say "non-exist domain" on my PC

3) "nslookup CHERRY.BRAVO.NET"

3a) will say "non-exist domain" IF I run nslookup on the server

3b) will give the correct IP address on my PC

Thank you for help.
