Can an IP like 62.249.*.* be gray?

Question

Computer networks

In general, the essence of the matter is, according to Google, certain subnets are reserved for gray IPs and this one is not among them, but at the same time, the server on ubuntu with the firewall disabled does not open to the outside, although there are no problems inside the local area, the question is whether the provider can white make the address gray if he wants?

Answer 1

try to enter the input data correctly: the
"server" is at your home, and you are wondering why it is not accessible from the outside there is no access from the
outside, because there are not enough Internet addresses in the 21st century for everyone, and the provider uses a dedicated block between all its users , i.e. in the provider's network, there is more than one of your "server" with this IP (hence the "static IP rental" service)
, while the hoster allocates an IP to the server (which can also be rummaged around, depending on the contract), but there will be routing to it from the outside, because that the IP is mapped to one interface.
you need to raise the VPN from the server IP to your computer server, and everything will work out, the VPN is two-way - you can also from your server to the VPN, only the address must be exactly only yours, i.e. you need a VPN on the VPN/Server, not on the VPN service

Answer 2

Do you want to look for other reasons? Just some fantastic ones?
For example, the ISP blocks ports that can be used for spam.
Or you incorrectly forwarded ports through the router.
Or you check accessibility outside from LAN.
And here you should be visited by the thought that we are not psychics. Few initial data.

Answer 3

Everything is possible in life - it depends on stupidity or genius :)
In general, the address is white, check the server, or, in extreme cases, call Provo (maybe he has some blocks). It is not entirely clear which service you cannot reach.

Answer 4

You go to myip.ru and look. If the IP of your machine matches what the site showed, it means white.
Purely hypothetically, of course, you can wrap 62.249 .. as an internal one, but this is a hemorrhoid, so you can not consider it.
It is easier to assume that either the service is incorrectly raised (for example, it listens only to the local interface), or the provider blocks certain ports, which occurs.

Answer 5

Is the address static?
Have you forwarded ports?
