This is interesting. Do you know who controls these public addresses? I know in the past I've seen filtered connections to 192.x.x.x thinking that it would get only internal connections then. The owners of these public addresses could wreak havoc in some places.
- benjarrell 13y agoFrom http://tools.ietf.org/html/rfc1918 http://tools.ietf.org/html/rfc1918 The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets: 10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
- randomdata 13y agoRFC1918[1] defines 192.168.x.x as the private address space, so anything else in the 192.x.x.x range would not fall under that specification. [1] https://tools.ietf.org/html/rfc1918#page-4 https://tools.ietf.org/html/rfc1918#page-4
- oasisbob 13y agoThere's a university with a 192.16x.x.x allocation who has written about the confusion it's caused. Nothing that special about it from a CIDR point of view -- but is rather confusing to us humans when written as a dotted quad. Github's GITHUB-NET4-1 is on 192.30.252.0/22, which is what reminded me of this.
- cbhl 13y agoHeck, the University of Waterloo has 129.97.0.0/16, and I see people get confused all the time between 192.168. (private) and 129. (publicly routed).
- glitch003 13y agoI have a 192.40.x.x address assigned to a VPS I have from a small random hosting company in colorado.
- groovylick 13y agoI got 3 192.x.x.x addresses from Ramnode for one of my nodes. They can't be that rare.
