Load balancer for our application myloadbalancer.myorg.net returns either of the active IP ( 165.a.b.c or 165.x.y.z ). If we keep an entry in /etc/hosts file for load balancer like below

0.0.0.0/0      myloadbalancer.myorg.net     alias_name

will load balancer still work in same way as it is working now and will return active IP ?

Can i also provide entry like below

165.0.0.0/32     myloadbalancer.myorg.net   alias_name

Which will work more efficiently ?

Thanks in advance.

summary

You can have only single IP address in /etc/hosts entry, not the network. Your first example `0.0.0.0/0` denotes the whole Internet, and `165.0.0.0/32` makes no sense. – Yuri Ginsburg Apr 14 '21 at 22:57
Does that mean entry => 0.0.0.0/0 myloadbalancer.myorg.net alias_name will work . The default IP out of whole network will be returned ? – summary Apr 15 '21 at 05:03
The 2nd entry represents CIDR classless IP addressing . – summary Apr 15 '21 at 05:55
length /32 means 1 host. – Yuri Ginsburg Apr 15 '21 at 08:17
165.0.0.0/2 myloadbalancer.myorg.net alias_name Will this entry work ? – summary Apr 15 '21 at 10:19

No. __You can have only a single IP address in /etc/hosts entry, not the network__. Also `165.0.0.0/2` represents a network of 1073741822 IP addresses in a range `128.0.0.1 - 165.255.255.254` – Yuri Ginsburg Apr 15 '21 at 21:40

which IP will be called if /etc/hosts has entry 0.0.0.0/0 for load balancer
