Convert hexadecimal ip address to decimal dotted from TMG

[amedrano]

Hello, 

I am looking for a way to convert the column ClientIP from TMG database into a legible IP address, the value is in the format:

C0A8019A-ffff-0000-0000-000000000000

the first 8 characters are the ip address in hexadecimal: 

C0A8019A = 192.168.1.154

C0 = 192

A8 = 168

01 = 1

9A = 154

thanks

A Power Query solution:

let
    HexDigits ="0123456789ABCDEF",
    Source = #table(type table[ClientIP = text],{{"C0A8019A-ffff-0000-0000-000000000000"}}),
    First8Characters = Table.AddColumn(Source, "IP Address", each Text.Start([ClientIP], 8), type text),
    SplittedIntoPairs = Table.TransformColumns(First8Characters, {{"IP Address", Splitter.SplitTextByRepeatedLengths(2)}}),
    SplittedEachPair = Table.TransformColumns(SplittedIntoPairs,{{"IP Address", each List.Transform(_, Text.ToList)}}),
    HexToDec = Table.TransformColumns(SplittedEachPair,{{"IP Address", each List.Transform(_, each 16*Text.PositionOf(HexDigits,_{0})+Text.PositionOf(HexDigits,_{1}))}}),
    PartsCombined = Table.TransformColumns(HexToDec,{{"IP Address", each Text.Combine(List.Transform(_, Text.From),"."), type text}})
