📄 Description

The peer IP allocation logic was allocating sequential peer IPs
e.g. 100.64.0.1, 100.64.0.2, etc. from the 100.64.0.0/10 range.
Each account is created with a random subnet from 100.64.0.0/10 range. The total amount of potential subnets is 64. This gives us an option to "physically" groups peers on a subnet level.
The new logic allocates a random peer IP
from the account's subnet.

Example:
Account was created with a subnet 100.75.0.0/16.
New peer was added with an IP 100.75.65.8.
