Virtual hostname and IP address range

[Former Member]

Hello

In order to install SAP system based on virtual hostname for linux operating system, is there an recommendation or an restriction

to setup IP adresses from the same range ?

<ip1> physhost.domain. corp physhost

<ip2> virthost1.domain. corp virthostv

As far as I know there are no restrictions from SAP.

There may however be restrictions from your network team.

Hello Eric,

Do you mean that the physical hostname will be assicoatd to the IP 10.10.10.X (for example) and the virtual hostname would be mapped to 10.10.10.Y?

If the above is correct, there are no issues from the SAP end.
