Twitter and Subnets Query

I use Follow Liker and use private proxies.

However out of 20 private proxies, they're divided into 3 groups, each group starting with the same 9 numbers, with only the last 3 being different.

Now, if Twitter ever suspends an account, I'm finding any account also using an IP with those first 9 digits, also gets suspended. As you can see that can be a huge number of accounts, if I'm running 4-5 on each IP.

So my question is, when purchasing Private Proxies for Twitter, do I need the IPs having only the first 6 digits being identical, or would Twitter still ban all 123.456.xxx.xxx proxies?

Better to get Ips from that provider who does provide Ips from multiple subnets like 3-5 for that no of Ips.

it will make them looks more diversified and safe your accounts and time too.
