Tcp.dstport != 80 suffers from a similar problem having tcp.dstport != 80 turns out to mean 'match ONLY tcp traffic, but only tcp that is not dstport = 80' Here's a complete example to filter http as well: not ip.addr = 192.168.5.22 and not tcp.dstport = 80 For example, when connecting to 192.168.5.254 from 192.168.5.22, ip.addr != 192.168.5.22 doesn't match *.22 IP, it matches *.254 and thus the packet matches the filter expression.

It might seem more logical to write it as ip.addr != 192.168.5.22, but while that's a valid expression, it will match the other end of the connection as not being the specific ip and still be true. You could also write it like so: not (ip.addr = 192.168.5.22) With the negative match like you have, you need both conditions to be true to filter off your IP, thus and instead of or. A RIR is a nonprofit organization that allocates IPv4, IPv6 and ASN (Autonomous System Numbers).Mitch is right. The answer is simple, from one or more RIRs (Regional Internet Registry). I hear you are asking “Where does one of the API get geolocation of an IP address from?”. When you are googling for ' What is my IP address?', It probably takes you to a site which is using that kind of API. There are many free services available on the internet as well as commercial ones which provide some sort of an API (Application Programing Interface) to their clients. With help of IP geolocation, we can find geographic location of an IP address. Especially when we do network forensic analysis which aims to detect attack patterns and identify attackers. There are times when we need to trace an IP address back to its origin (Country, City, AS Number etc.).
