Your external IP address is assigned to you by your ISP. Your internal IP address is generally assigned to you by your router, which is often the device provided by your ISP. You cannot clean them out. If you turn off your router for hours at a time you may be assigned a new IP address due to conflict when another device was assigned the IP your router had previously been assigned. You can discover your external IP address by typing What Is My IP into a search engine such as Bing and clicking on the first non advertiser results. If it is changed it will not move by more than a couple of octets because they are assigned from a pool by the ISP. ------------------------------------------------- (100.100.100.15 -> 100.100.99.20) Each of the fields between periods are called octets. This is because the IP scheme was developed in a world where hexidecimal (hex) had not yet taken control from Octal numbering in technology.) The odd thing about it being called an octet is that it is actually in hexidecimal. Base two is a single binary bit: 0 or 1. Base four is two binary bits 00 through 11. A byte in base 8 [octal] is three binary bits 000 through 111. A byte in base 16 [hex] is four binary bits 0000 through 1111. The numbering system like decimal refers to the (decimal) number represented by 10: 0001 0000. The value of each bit in a hex is 128\|64\|32\|16\|8\|4\|2\|1. Yes this is TMI, but included it case you were interested.
