STProxy Ultra
Ultra is STProxy's residential IPv6 proxy: instead of a datacenter IP, your number uses a real IP from a home internet provider — the same kind of address a phone or home router gets.
To platforms like WhatsApp, traffic coming from a residential IP looks as natural as it gets — which is what makes Ultra the favorite tier for numbers that need strong reputation.
Who Ultra is for
- Numbers doing broadcasts and prospecting that need the best possible connection reputation.
- Anyone who has had blocking/instability issues and wants a more "human" IP profile.
- Operations that value on-demand IP exchange (see below).
How it works
- You get a dedicated residential IPv6 IP — a real home-provider address, exclusively yours.
- Once applied to the instance, that number's WhatsApp always connects through that IP.
- On-demand exchange: unlike a traditional fixed IP, with Ultra you can request an IP swap whenever needed — useful to refresh the address's reputation without changing plans.
One proxy per number
Each Ultra IP serves one instance. For multiple numbers, get one Ultra for each.
