• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Subnet mask

New Pleskian
I've never seen this explained well: When you add an IP address, there is a subnet mask, but no help about what that means, and no examples.

I have a Plesk PC doing just simple straight hosting of a dozen domains and 1and1.com and these [fictitious] IPs:

111.222.33.44 255.255.255.255 (came with the box)
111.222.88.1 255.? (nameserver 1)
111.222.88.2 (nameserver 2)
111.222.88.3 (shared IP between domains)
111.222.88.4 (exclusive IP for some domain)

What should the subnet mask be for the latter three?
