IP address conversion

[desperado]

Hi
I have a column with IP address 
I want to do following:
Excample Ip address 172.180.180.34

Octet 2
Take the number from octet 2 and substract it with 176. Get the number and choose a character from a variabel
Variabel = "0123456789abcdefghijklmnopqrstuvwxyz"
So if the octet 2 is 180 the result would be:
180-176 = 4
Value after postion 4 from the variabel = 4

Octet3
Convert the number to hex
So octet 3 is 180 and would be B4

Result in new column
result octet 2+result octet 3
3B4

Ladies & Gents
This is my first Power Query function.
Based on above scenario here is what I figured out.
-------------------------------------------------------

let
IP2Number = (

IP as text

) => let

currentIP = IP,
Alfa = {"0".."9"} & {"A".."Z"},
ListOfOctets = Text.Split(currentIP, "."),
Octet2 = Alfa{Value.Subtract(Value.FromText(ListOfOctets{1}),176)},
Octet3 = Number.ToText(Value.FromText(ListOfOctets{2}), "x"),
Result = Text.Combine({Octet2, Octet3})
in
Result

in
IP2Number

-------------------------------------

Please le me know if it's correct thinking

After testing, I need to have a check on the value of octet2.
If the value of octet2 is negativ, then Result should be "unknown"

Not familiar with if's ....

Hi  @desperado ,

Modify your M code as below:

let
IP2Number = (

IP as text

) => let

currentIP = IP,
Alfa = {"0".."9"} & {"A".."Z"},
ListOfOctets = Text.Split(currentIP, "."),
Octet2 = try Alfa{Value.Subtract(Value.FromText(ListOfOctets{1}),176)} otherwise "unknown",
Octet3 = Number.ToText(Value.FromText(ListOfOctets{2}), "x"),
Result = Text.Combine({Octet2, Octet3})
in
Result


in
IP2Number

And you will see:

Hi @v-kelly-msft 

Thank you for the answer.
It works for octet2, but I want as follow:
If octet2 is negativ, then skip octet3 and set result to "unknown"
So for IP 172.172.180.4 the result should be "unknown" and not "unknownb4"

Again, thank you for the reply

Octet2 = try Alfa{Value.Subtract(Value.FromText(ListOfOctets{1}),176)} otherwise "unknown",
Octet3 = Number.ToText(Value.FromText(ListOfOctets{2}), "x"),
Result = Text.Combine({Octet2, Octet3})
in
Result

Hi  @desperado ,

Then use below code:

let
IP2Number = (

IP as text

) => let

currentIP = IP,
Alfa = {"0".."9"} & {"A".."Z"},
ListOfOctets = Text.Split(currentIP, "."),
Octet2 = Alfa{Value.Subtract(Value.FromText(ListOfOctets{1}),176)},
Octet3 = Number.ToText(Value.FromText(ListOfOctets{2}), "x"),
Result = try Text.Combine({Octet2, Octet3}) otherwise "unknown"
in
Result


in
IP2Number

And you will see:
