An address launched an attack on my computer this morning

Heze City, Shandong Province Netcom.

The IP database is a human census, and if someone counts the county, he has the IP segment of each district of the county, which is basically always changing. So you see that the first two are the same, the first two are the same, and you can't be sure that they are in the same range, and the first three are not necessarily the same.

First of all, now the domestic IP address segment is randomly distributed and miscellaneous, I think few people know which operators are which ones, I can only briefly talk about my personal experience and impressions.

Netcom's segment starts with 6x, starts with 210.

218 starts.

Telecom Segment 219 begins with.

222 starts.

124 starts.

Unicom 211 starts.

220 starts.

The beginning of 202 is Netcom Telecom, the 202 in the south is Telecom, the 202 in the north is Netcom, Han... It depends on which side you are.

You can roughly indicate which exit to take according to the above paragraph.

My personal opinion about it. In fact, there is no need to be so complicated, because Netcom Telecom is also constantly expanding and interoperating, and our Northern Telecom is said to be not as fast as our Netcom, which makes these telecoms angry to death (it seems that Netcom Telecom has signed an agreement, in short, it is a weak loss). I think the most practical thing is to do a diversion, if the two exit rates are the same, half go and the other will go the other.

Or go to someone from telecom or Netcom and ask him to check the domestic network segment for you, and then point it to you, which is very troublesome.

of your inquiry.

Heze City, Shandong Province Netcom.

Just for a database called SQL.

The software that is supported is he on port 1433.

Since the network standard is reflected, it's fine, not to mention that the 1433 port personal computer is not turned on at all? There is no SQL database.

Leave it alone, your next 360 firewall will automatically block this kind of attack, this attack won't be intentional, I guess you have a LAN bar. You don't have to worry, it's fine.

It is in 1433 and 1434 bars. The IP is assigned by the network ** business, and if you want to check it specifically, you have to go to the corresponding business hall. SQL is a database, and most personal computers don't have it, so since it's blocked, it's fine.

The allocation of IP addresses is made by your cat to the merchant, and the merchant's server receives it and sends you an idle IP as a path to surf the Internet. That's it.

It's okay if this hack is intercepted, don't worry.
