IPv4 and IPv6 Subnet Calculator App Reviews

I would very much like an update for the 6S Pluss larger screen. Also a modern UI would be nice

I just want to say I rarely write reviews but this app I needed to. This application is fantastic it has help me with my CCNA studying and of course thus helping me find out information of IPv4 addresses for subnetting schemes. The only two things I wish that It gave you is the number of hosts bits and the number of Network bits. If this app would provide that it would be a big help. Thanks

I just bought this app based on the stellar reviews, but I am disappointed. As a tool for planning a network, it leaves a lot desired. If you have an IP and a subnet mask, and want to know details about the network that address belongs to, its ok. As others have mentioned, you cant enter the subnet mask using the bit notation, which is a huge pain. If you are planning a network, you want to be able to enter a network address, play with subnet masks, and go from there. This doesnt serve that purpose. The interface also looks really dated on an iPhone Plus. This app hasnt been updated in quite a while, but I hope it gets a facelift.
