Dear all, As we see ISPs and community would like to have more IPv4 space in use. I would like to ask a question what do people think about other side of IPv4 numeration space. Because we have in IPv4 a lot of addresses not in use at all but that space could be easy used. 240.0.0.0/4 Reserved (former Class E network) RFC 1700 it's 16 */8 networks. More then 256 Millions of routable and never used IPv4. 185/8 network has about 6.4M free and total RIPE has about 15M free IPv4 and we all say 185/8 will be enough for 2-3 years and rest - for some more time. But 256 M Ipv4 space could be enough for years! Space reserved for future Use. But will the future come to us or not? https://en.wikipedia.org/wiki/IPv4 https://tools.ietf.org/html/rfc1700 Is far as I see routers could easy start to use that IP space. People spend a lot of time and money to get some IPs but not to ask IANA to allow use this space. Technically it's very easy to start use IPs from such ranges. What does community thinks about it?
