Wow, sounds good!
How this can works, can you explain?

I know about EmerCoin SSH and you can see here https://emercoin.mintr.org/nvs/
if you will search by type, the next types for domain names:
dns, hmt, dpo, and... SSH domain names
As I know VPN using too by Secure Shell technology (SSH) but this is not VPN-service.


Hm... I know about your post here: https://bitcointalk.org/index.php?topic=1235629.msg12868191#msg12868191
But, your derivo - not working,
http://3g2upl4pq6kufc4m.tor2web.org.derivo.611.to - not working
and your {"alias":"3g2upl4pq6kufc4m.tor2web.org.derivo.611.to."} not working.
https://ddg.611.to not working too.
tor2web.org - lagging sometimes.
Yeap, TOR is anonymous service but IMHO, this is better then DDNS for servers,
because DDNS need clicking for update IP or using additional programs regularry...

I have the site on the onion domain: http://42k5tcpg7bhjjaze.onion/ and this site can be opened from Tor Browser.
But to have access from Internet, I need to using https://tor2web.org/ instructions
and change the link: https://42k5tcpg7bhjjaze.onion.to/ (another domain zone not working for me)

This service (tor2web) is lagging sometimes, and I can see an connection errors.
But sometimes I can get access with this service and can using,
for example, brainwalletX_XOR there - without any DDNS:
https://42k5tcpg7bhjjaze.onion.to/BrainwalletX_XOR/from_this_site/
I have HFS server there and this do listing port 80 on my localhost,
and brainwalletX working from this server, because this is unpacked.

But... http://42k5tcpg7bhjjaze.tor2web.org.derivo.611.to/ this is not working...
So I cann't using this as alias... Also, there is tor2web-header...
