New blog post 📰! What happened the last 9 months around MPTCP 🔀, and which new features will be available in the future LTS v6.18 Linux kernel version: https://blog.mptcp.dev/2025/10/16/v6.18-with-many-features.html

- Better load-balancer deployment support on the client side 🔄
- New 'laminar' endpoints for better controlling addresses signalled by a server 📢
- mptcpd: security review and improvements 🔐
- More apps natively supporting MPTCP 🧑‍💻
- Misc.: PM, counters, CI, perf, socket options, adaptive ADD_ADDR timeout and future work. 📈

MPTCP or Multipath TCP is an extension to the standard TCP to allow devices to make use of multiple interfaces at once. See https://mptcp.dev for more details.

Thanks to @nlnet for funding part of this work 🎉

Summer update and MPTCP features in Linux v6.18

Long time no see (or read?) as we could say! The last update was in January. Since then, we have been very busy! Read on to find out what happened around MPTCP during the last few months, and which new features will be present in the future v6.18.

AKSHUALLY, YOU ARE CHEATING!

No seriously, the idea of #MultiLinkPPP isn't new and in #EDGEland aka. #Germany there a company to this day called #Viprinet who's CEO & Founder actually patented both mixed-technology link bonding and transparent applianced devices to facilitate these links, allowing for transparent redundancy, bonding, speed and low latency, without packet drops and on-the-fly speed changes.

And unlike #MultipathTCP and #PPP - #MultiLink setups or #MPLS it's actually an encrypted #VPN and can transparently allow all #IPv4 & #IPv6 packets through it - including #UDP - whilst not requiring cooperation from the #ISPs and being able to arbitrarily connect anything from ISDN to Cable and from 2G to 5G as well as Ethernet and WiFi...

The main selling point is that it reduces costs compared to #SDSL with guaranteed SLAs, so a link failing would merely slow down the speeds transparently.

So yeah it makes sense in nieche applications...

#MultipathTCP on #Linux. I'm not expert enough to know how exactly that works or what it's doing, but it seems to be making one of the protocols on the bedrock of the #Internet more resilient, which is always a good thing 📡

@jwildeboer @EU_Commission that being said, #DTAG are shit as #ISP and forcibly disconnecting & reallocating IP adresses is the norm on ALL consumer tariffs with no SLAs whatsoever.

There's #DynamicDNS, #MultipathTCP and #VPN as well as @torproject #OnionService|s for that scenario!

I specofically have an Enterprise Tariff to avoid these pitfalls...

It's 2023 and my German internet provider (DTAG) still forces a change of public IP (v4 and v6) address every 24 hours ATM for me, making sure I cannot run my own services reliably from my server at home. UPDATE: Changed the wording to reflect my individual problems, as it seems others do not have these effects. Still: you cannot get a dedicated IPv4 address or IPv6 range as a home user/domestic customer.
