har man nogen muglighed hvis man ikke ønsker, at bestemte hjemmesider skal besøge ens side, men man kender ikke deres IP nr. kan man så fange deres IP nr.
for det er jo også en muglighed for, at begranse alle de uheldige i, at lægge snavs ind.

AVG viser et IP nr når man stiller sig på siden, hvad er det for et IP nr. lægger et skærmbillede ind så du kan se det, øje
Jeg vil tro at det ipnummer er till ham der har den side du holder musen over.
sikkerheds systemet kan jeg skaffe til dig men det bliver iaften så her skal du så lige vedhæfte din maincore så jeg lige kan rette den til
jeg kan ikke indsætte fil den er væk på siden, hehe hvor har du gemt den, så det bliver en være lang kode hihi
