Former Cuckoo UK broadband users left confused over Onestream’s stance on static IPs
Some customers of broadband ISP Onestream, specifically those who were bulk migrated from Cuckoo after the customer base was sold in May 2026 and previously had a static IP address (here), have complained after they were put on CGNAT (IP address sharing) connections and given mixed messages about future static IP support.
According to some of the feedback ISPreview has seen, impacted customers were initially told that Onestream was aware of the issue and working to resolve it, although at least one support agent speculated that this might require subscribers to agree a new contract. We should point out that Cuckoo currently still seems to be handling most of the support responses for migrated customers, which is a little unusual.
One of our readers, Michael, who was affected by the same issue, then lodged a complaint over the matter and was this week told by the ISP that “we do not currently offer IP addresses without CGNAT … we understand that this may not be the outcome you were hoping for, and we regret any disappointment this may cause.” The reply did not mention any plans to introduce the missing feature.

Onestream has since confirmed to ISPreview that a “product update” resulted in 88 of their customers being affected by an “issue” with their static IP services, but the good news is they are working to resolve this. “We are proactively communicating with those customers and expect to have their normal service restored very soon,” said a spokesperson for the ISP.
At least some of those impacted are known to be on APFN’s underlying full fibre network. But despite yesterday’s news we note that Olilo, which is one of the few other ISPs on the same network, doesn’t yet appear able to support direct ISP migrations (i.e. only new customer connections on APFN). Suffice to say, Onestream’s customers in this boat don’t currently have many options but to wait for a solution.

Another company whittering “we understand that this may not be the outcome you were hoping for”, it’s such an irritating sentence, like a computer trying to gently let someone down. I presume this is a standard output of AI, I see it more and more these days.
I’ve got a static IP as an ex-Swish ex-Cuckoo customer and don’t seem to have been impacted yet. They’re billing me for it so their billing system knows it is possible.
I am eagerly awaiting switching being possible so I can move over to Olilo however.
The comedy act continues.
