I'm a techie too but I think:
- If you go around memorising addresses then you are doing IT wrong in general. So many things depend on DNS (not just A records) that punching in IPs by default is a bad habit. Browsers will keep on enforcing SSL/TLS more and more until the point where typing in an IP address into the URL bar will be as painful as using the web GUI for say an elderly HP switch is right now.
- In general latency is not affected by header lengths these days. In some cases, networks are prioritising IPv6 for the opposite affect. In other cases ISPs have dropped their entire IPv6 support without noticing for quite some time. sigh
- The addressing scheme in use should have nothing to do with your privacy. Yes NAT does accidentally hide you a little bit. However I can fingerprint your browser instead, for example. I'll trade easy SIP n RTP over NAT any day.
Now, for my gripes:
- Try doing multi WAN effectively over IPv6 without PI and a routing algorithm, or NAT
- Try changing ISP (new addressing everywhere)
The second gripe I currently work around with RFC 4193 - Unique Local IPv6 Unicast Addresses, the first one I whine about and will probably use NPT (wholesale NAT for IPv6)

Most of the things I do with memorised addresses have nothing to do with the browser or HTTP. (Mind you, though, the moment a browser won't let me access a bare IP, I'm switching away from that browser.) > - In general latency is not affected by header lengths these days.

Yes NAT does accidentally hide you a little bit. However I can fingerprint your browser instead, for example. I'll trade easy SIP n RTP over NAT any day. A website I navigate to may, but how will the carrier fingerprint my browser? All in all, it seems like we are talking about very different threat models to privacy/security. You are worried about the likes of Google and Facebook profiling you, whereas I am worried about the likes of $intellectualpropertymonopolist sending me a $20k bill for identifying me in a torrent, or experiencing a nasty surprise at $nationalborder (or at home, [1]!) for something I said on an internet forum. (This does not seem like an abstract or overblown threat to me; I've seen 2 out of the 3 things above happen to friends and even one schoolmate more than 2 times.)

- gerdesj 8y agoMost of the things I do with memorised addresses have nothing to do with the browser or HTTP. (Mind you, though, the moment a browser won't let me access a bare IP, I'm switching away from that browser.) Me too. Wireshark, nmap and co are in regular use in my job. All browsers are playing nanny, more and more apart from the likes of Links (which I also use quite often). A lack of https is already flagged and I suspect that things will get worse in this regard. Links2 has saved my bacon many times in the past so you may enjoy it 8) You are worried about the likes of Google and Facebook profiling you No mate. I'm CREST accredited: I'm not worried about G and F profiling me - I know they do. However I also know that my choice of addressing scheme does not affect my privacy whatsoever. A carrier can use metadata to derive loads of facts about your usage even if you are connecting to the oher end over say https. NAT will save you from some silly firewall screw ups but not much else. A VPN can help but is no silver bullet either. If I really put my mind to it I could probably make myself near enough anonymous with enough use of proxies, VPNs and TOR but I'm not too sure about that! I too am from the UK and have seen silly overreactions such as your [1] link. However, this is the world we have nowadays and in our case we have a horrific level of CCTV pointed at us as well as some pretty impressive levels of IP traffic mining. We also have the rather unpleasant RIP Act and a few others to belie our supposed liberal way of life in the UK. You do have to be careful what you say nowadays, within reason.
- 4bpp 8y agoWell, my assumption was always that in a scenario such as: ISP makes me share my public-facing IP with 15 randos -> I get on a torrent for Sony Corporate Secrets [full pack] [2018].zip -> Sony's legal department connects a honeypot and harvests all IPs it sees on it and sends out subpoenae to identify everyone who is in a friendly jurisdiction, the circumstance that I'm NATted by my provider will actually do nontrivial work in reducing the probability that I am ultimately identified in a legally actionable way (especially if it were to take Sony a while to process its data). Is this not accurate?
- pseudalopex 8y agoYour ISP would usually have port mapping logs.
- pedrocx486 8y ago>- If you go around memorising addresses then you are doing IT wrong in general. Because I'll surely have an TLD for my local nginx and for my home router...
- gerdesj 8y agoYou can buy a DNS domain for a few quid per year or you can use a dynamic DNS service such as freeDNS for err free. If you go around exposing services on the internet then you should know how to do it properly. If you can get a name on it then you can put a SSL certificate on it (cheers Lets Encrypt). If you have a SSL cert on it then you can be fairly sure you are talking to your gear and not a MitM if you take other precautions. I absolutely do have a LE SSL cert for my home router and all my home web sites. pfSense has a ACME and dynamic DNS client for many services and HA Proxy built in. What more could you want!
- Osiris 8y agoWith IPv4 you don't HAVE to buy a domain for your local network. You can do just fine with IP addresses. With IPv6, you probably will need to just to make it sane. That adds a whole new step, and a complex one that most people (general public) won't know how to do.
- Wowfunhappy 8y agoTo be fair, most of the general public doesn't know what an ip address is. I'm in the group that you're speaking of—I have a personal server set up that I can log into remotely, but the prospect of setting up a domain and TLS is very daunting. But, I don't think people like me are all that common.
- gbrayut 8y agoJust use home.arpa from https://tools.ietf.org/html/rfc8375 https://tools.ietf.org/html/rfc8375 with a custom DNS server or host file. Or one of the many dynamic DNS systems.
- protomyth 8y ago> If you go around memorising addresses then you are doing IT wrong in general. So many things depend on DNS (not just A records) that punching in IPs by default is a bad habit. If you are debugging network connectivity, then I have a tough time believing it’s possible without typing in a few network addresses.

Browsers will keep on enforcing SSL/TLS more and more until the point where typing in an IP address into the URL bar will be as painful as using the web GUI for say an elderly HP switch is right now. This heavily reminded me of the good old Night Watch essay[1]. You can punch DNS names into the address bar on a browser, because someone out there traded normal sleep schedules for the tremendous opportunity to think about BGP trees, netmasks, and other exciting arcana.
