Are you ready for the end of IPv4 address availability? IPv4 addresses are running out. Estimates currently have the available IPv4 address pools allocated to the regional registries starting to run out in 2011. Track the rate of IPv4 allocations easily with this application. Is the progress of IPv6 deployment and usage important to you? IPv6 is the next-generation IP protocol with a significantly expanded address space. IPv6 includes additional enhancements to security, management and network design. Track the growth of IPv6 deployments with ease. Links to a number of IPv6 informational sites and videos are also included. ## Key features - Track IPv4 allocation rates - Monitor IPv6 deployment growth - Access IPv6 informational resources - View IPv6 videos ## Recent user reviews (10 of 11) All indexed reviews: https://appshunter.io/ios/app/byebye-v4/id317969597/reviews.md ### 5/5 — RIPE NCC *2018-07-20, version 2.2.8* RIPE NCC counts now show a negative number. ### 3/5 — Shows count of addresses remaining at 5 registries, that's about it *2012-11-13, version 2.2.5* When I saw a update for this app on the App Store, at first I was excited, but then realized it was only to add iPhone 5 display sizing, as is required of all apps in the App Store these days. I'm glad they now show the IPv4 addresses remaining at the 5 regional distributors of IPv4 addresses: ARIN and so on. Even though IANA is out, these regional registries still have a few addresses left. This app does its job, however it doesn't really provide much benefit to the user. As others have said, it would be nice for them to throw in some sysadmin tools such as IPv4 and IPv6 subnet calculators, or whatever else they might deem useful. The IANA page on the app is useless, as it's always 0 these days. The Hurricane Electric page is just a global map showing Hurricane Electric's physical locations, useful only as advertising material to demonstrate Hurricane Electric's very good global connectivity. The user can't interact with this page in any way, though. The most useful page is the readout of the 5 regional registries, which could be accomplished with a simple webpage. It doesn't need to be an app. Since Apple only allows 11 pages of apps (even on iPad!), I can't justify this app remaining on my device. ### 5/5 — Thank *2011-07-17, version 2.2.1.539* Thanks ### 5/5 — interesting app, does what it says *2011-04-17, version 2.2.0.523* Thanks HE for making this app. Would be nice to add some IPv6 features, maybe some v6 ping and v6 traceroute to give it some utility. ### 5/5 — Yep, Does What It Does *2011-02-01* Does it well. Relevant. Useful. And fun. Unless you're a UK ISP, of course; in that case, it's your worst nightmare, or it's already taken care of! ### 4/5 — Feature suggestion *2010-11-09, version 0* Would like to see a "check my IPv6 connection" tab added to this app now that iOS supports IPv6 for wifi. ### 5/5 — Countdowwwwwnnnnnna *2009-11-09* This is the official count down for when we run out of ip addresses on v4 and the count up to ipv6. Thats it thats all. 5 stars punk ### 3/5 — Nice but not really useful. *2009-07-09* 3 stars as it is coded well but not really useful otherwise. Was hoping to be able to manage my HE tunnel. ### 5/5 — Nice presentation *2009-07-06, version 0* I have watched these stats in a browser for a while, but it is great to have them on my phone now too. Thanks! ### 4/5 — IPv6 is our collective future *2009-06-12, version 0* Finally... A clean portable way of showing people the exhaustion of v4. Love it! There aren't many days left. It's time to implement IPv6! ## Frequently asked questions about ByeBye v4 ### What is ByeBye v4 used for?
