The new generation of alternative gigabit-capable broadband ISP networks (AltNets) has helped to bring a huge amount of additional competition into the wider UK market. But one area where some of them fall down is in their use of technologies like CGNAT (IP address sharing) and the lack of IPv6 support.<\/p>\n

Now, it’s fair to say that many ordinary consumers probably won’t care too much about things like this. But for IT people, as well as online gamers and those with particular security requirements, the approach an ISP takes to the use of Carrier Grade Network Address Translation<\/strong> (CGN), and any related support for the Internet Protocol v6 (IPv6) addressing standard, can make all the difference.<\/p>\n

NOTE:<\/strong> The issues described below are less of a problem for the often bigger and more established ISPs, most of which have already secured plenty of spare IPv4 addresses and so have more flexibility to adapt.<\/div>\n

First, a little explainer. Everybody needs an Internet Protocol (IP) address to go online and your ISP is responsible for assigning one to your connection (it\u2019s the internet equivalent of a phone number). Most ISPs tend to use Dynamic IP<\/strong> addresses for domestic connectivity, which changes each time your broadband link is disconnected and isn\u2019t shared with other subscribers (at least not at the same time you\u2019re using it).<\/p>\n

Some providers will also allow you to take a Static IP<\/strong> (Fixed IP) address, which remains the same no matter how many times you switch the connection on and off, albeit usually at an extra cost. However, the shift from the old IPv4 system, which has long since run out of spare addresses (buying IPv4’s now on the market is an expensive business), means that in order to add new connections some ISPs have had to adopt CGN.<\/p>\n

CGNAT enables a single IP address to be shared between many users, and is thus seen by some ISPs as a useful solution for IPv4 shortages. But sharing IP addresses like this can also cause security and connectivity issues, which is something that more advanced users often prefer to avoid.<\/p>\n

One way to reduce the negative impact from this is to ensure that the network supports the latest IPv6 addressing standard, but surprisingly there are still plenty of ISPs that have yet to properly adopt it. The reality is that some providers will need CGNAT until IPv6 has fully taken over, thus in the meantime more advanced users tend to look for ISPs that can mitigate this by both supporting IPv6 and offering Static IP addresses.<\/p>\n

Surveying AltNets<\/strong><\/span><\/h3>\n

The problem is that most AltNets, as well as ISP more generally, tend not to do a good job of communicating their use of CGNAT or IPv6 support. In addition, CGNAT support may vary between packages (e.g. you might see it on cheaper residential plans, but not necessarily the business variants of those). This can make it very difficult for more advanced \/ experienced users to figure out whether the new networks are able to cater for their needs.<\/p>\n

In recent years’ we’ve seen quite a few complaints about this, and so we’ve today responded by surveying each provider to identify their level of support. In cases where we couldn’t find enough consumer feedback to verify the details, then we’ve manually contacted providers to ask three simple questions:<\/p>\n

1. Do your consumer broadband packages all support IPv6?<\/p>\n

2. Do you offer a Static IP option to customers, and how much does it cost?<\/p>\n

3. Do your consumer packages use CGNAT?<\/p>\n

Since manually surveying masses of AltNets would be far too laborious, we’ve instead opted to only focus on those with wider UK coverage (ideally in the tens of thousands of premises). We’ve also excluded any providers \/ networks where we had no solid or recent data on their coverage.<\/p>\n

One catch here is that some operators are pure wholesale networks, which sometimes don’t operate their own optional retail provider, and in those cases we’ve opted to select two or more recognisable ISPs to represent them (note: IPv6 support is implemented at ISP level). Some of the ISPs we pick may be available via other networks too, but we try not to repeat the entries.<\/p>\n

\n\u27a4 Static IP Available: Yes (\u00a36 a month – or included on their ‘Gamer’ package)
\n\u27a4 CGNAT on Consumer Plans: Yes<\/p>\n

NOTE:<\/strong> We had to get some extra clarification on this one, since ‘Static IP’ above has a different meaning with Lila. “We unfortunately do not offer a strictly Static IP at this time, we do offer Public IP’s that are delivered dynamically, however unless a change is forced (on our system) the IP does not change, so it acts as a Static<\/em>.” So if you pay \u00a36 extra for one, you’re actually getting a Public IP that rarely changes.<\/p>\n

\n\u27a4 IPv6 Support: Yes

\n\u27a4 IPv6 Support: Yes – partial (full native IPv6 being deploying during H1 2024)
\n\u27a4 Static IP Available: No (but their IPv4s are quite sticky)
\n\u27a4 CGNAT on Consumer Plans: Yes and No (didn’t use CGNAT when asked, but was due to be added by end of 2023)<\/p>\n

NOTE: Ogi<\/a> said that, once CGNAT is deployed, they will be able to optionally put customers back on an IPv4 address (we assume a static one) if they have problems that cannot be resolved. But the roll-out of native IPv6 should help to placate a lot of this.<\/em><\/p>\n

Please note that the above details were gathered gradually over three months between late 2023 and early 2024. As a result, it’s entirely possible that some of the information may have changed since we last checked, and we also weren’t able to fill in all the blanks (not everybody responded). Suffice to say, we’d very much appreciate it if the providers and our readers could help by informing us if any of this information needs updating.<\/p>\n

UPDATE 11:11am<\/strong><\/p>\n

We’ve made a few updates to the listing following some useful feedback from readers and ISPs. I’ve also added Alncom after the provider submitted details.<\/p>\n

UPDATE 19th June 2024<\/strong><\/p>\n

Updates to GoFibre<\/a>, Seethelight, Hey! Broadband<\/a>, Gigaclear<\/a> and Lightspeed Broadband<\/a>.<\/p>\n

UPDATE 28th Aug 2024<\/strong><\/p>\n

Added MTH Networks.<\/p>\n

UPDATE 11th Nov 2024<\/strong><\/p>\n

One Quickline<\/a> customer reports that the ISP is now using CGNAT on their consumer plans, making the previous “No<\/em>” statement uncertain.<\/p>\n

UPDATE 3rd Dec 2024<\/strong><\/p>\n

Confirmed Quickline<\/a>’s move to CGNAT via more customer feedback, but customers can request a move back to native IPv4 “if they have a valid technical reason<\/em>“.<\/p>\n

UPDATE 3rd Feb 2025<\/strong><\/p>\n

Updated Static IP price on Grain to \u00a35.99.<\/p>\n

UPDATE 19th March 2025<\/strong><\/p>\n

Updated Gigaclear, now deploying IPv6.<\/p>\n","protected":false},"excerpt":{"rendered":"
