If only ARIN started to revoke IPv4 blocks based on this kind of waste.
- gardarh 14y agoYes, this is a perfectly good class C network wasted. What a shame.
- jlgaddis 14y agoIt's a shame that people are still (incorrectly) using the term "class C" 15+ years since classless addressing has been address too. =)
- gardarh 14y agotouché :)
- TranceMan 14y agoIt's a shame people still value and use IPv4 addresses when IPv6 has been around for 15+ years....
- zero_intp 14y agoIt's a shame people don't understand that IPv6 addresses are ~twice as costly to route. Not all things that are better are free.
- TranceMan 14y agoAre you joking? Citation?
- jrockway 14y agoConsidering computers double in power every 18 months, most people stopped caring about IPv6's extra overhead in 1994. (At some level, 128 > 32, so unless all the algorithms used for routing are constant-time over the addresses, IPv6 will always cost more. But if you add up a bunch of layers of NAT, that's not free either. So this argument boils down to "if nobody used the Internet, it would require less hardware to run". Well, yeah.)
- zero_intp 14y agowhile what you are saying is true, the upper bounds of all things limit the costs required to deploy infinite amounts of memory and processor cycles at scale. As always, a happy medium is required. That being said, once you boot up another stack, allocate various caches, and have your engineers maintain an additional set of configuration, the costs come down. But for ~10k routes, the costs to route those ips is greater than routing v4.
- packetslave 14y agoIt's in the middle of a /20 allocated to Epik Networks, and he's only using roughly a /27 of it. I think the Internet will survive. If ARIN did ever want to recover space, there are much bigger fish in the sea (I doubt Apple is using all 16.7 million IPs in their 17.0.0.0/8 allocation, for example).
- RKearney 14y agoHe's using much more than a /27 Each hop is using a /30. There's 47 useless hops in the mix before reaching the end. That's 188 IP addresses just wasted. Much, much more than a /27. In fact that's 6 times the waste of a /27.
- packetslave 14y agoYeah, using a /30 per hop is a bit of a waste, but one /24 is still insignificant to the Internet as a whole, especially when it's in the middle of a parent allocation. Presumably if Epik runs out of IP space in their /20, they'll just shut this down. It's not like some other company could use that /24. Again, if ARIN/IANA really wanted to reclaim "wasted" space, they'd be looking at the holders of big blocks like /8-16, and asking them to justify usage, not one random /24 which is ultimately insignificant.
- RKearney 14y agoBy that logic, petit theft is fine since the police should be looking for people committing grand theft and the petit theft is "ultimately insignificant" It's reasons like this why people now have to fill out forms justifying the need for additional IPv4 blocks.
- packetslave 14y agoYour analogy is nonsensical, since this is in no way "theft". He's borrowing some IP space inside an already allocated /20 that Epik isn't using at the moment. Epik already went to ARIN, said "we need a /20 to meet our IPv4 needs", filled out the paperwork to justify the allocation, and ARIN said "yes". Out of those 16 /24's, they have one that doesn't have any hosts on it at the moment, so they let him play with it. The only people this MIGHT be hurting is Epik, if they need to justify getting more space from ARIN at some point. For the other millions of people on the Internet: it's awesome. Lighten up and enjoy it. (edit: grammar)
