  • i buy my domains from namecheap but i use cloudflare for name servers (free tier, dns only for everything) and have ddclient (or whatever the newest version is called now) which runs on my router. my current settings only update cloudflare when the interface changes, and then update time after the change is about 15 minutes for propagation. i work in the network department of my isp so my address doesn’t change often, but the isp side of my setup is identical to any other subscriber. i use opnsense, but also manage a very small pfsense box that this works on as well. i update ipv4 dynamically, but not ipv6 yet, but i will.








  • Some service-provider level technology is not symmetrical at the access layer. An ISP serving exclusively fiber may have values like below:

    GPON (GIGAbit passive optical network): 1.24416 Gigabits/s up, 2.48832 Gigabits/s down

    XG-PON (10 gigabit passive optical network): 10G/2.5G

    xgS-pon (10g Symmetrical optical network): 10g/10g

    Note that on all of these technologies, you are also sharing bandwidth with neighbors on your PON. Sometimes up to 64 subs on one gpon. I think 128 on xgs-pon Until more providers make fiber available, as well as are willing to fork more up for the latest equipment, and reduce the over subscriptions of pons, symmetrical services for everyone just won’t happen.

    Will this ever happen at mega providers / baby-bells? Probably never unless a regional or startup pops up, and then they will only attempt compete in that market.
