Dette Python-skriptet følger en strukturert tilnærming til nettverksskanning, starter med minst invasive teknikker og går gradvis dypere. Det logger alle handlinger og resultater for enkel gjennomgang og analyse. `README.md`-filen gir en tydelig bruksanvisning, inkludert krav, installasjonsinstruksjoner, og eksempler.

### Forbedringer og kommentarer


- **Kodekommentarer**: Jeg har lagt til kommentarer for å forklare hva hver del av koden gjør.
- **Bedre struktur og lesbarhet**: Koden er strukturert for å være mer lesbar og vedlikeholdbar.
- **Feilhåndtering**: Enkel feilhåndtering er inkludert for å sikre at programmet fortsetter å kjøre selv om det oppstår feil.
- **Logging**: Loggfunksjonen skriver loggmeldinger til både konsollen og en loggfil, noe som gir enkel tilgang til resultatene.
- **README.md**: Bruksanvisningen er mer detaljert og strukturert for å veilede brukeren gjennom installasjon, kompilering og kjøring av programmet.

Dette gir en fullstendig, strukturert og godt dokumentert løsning for nettverksskanning i Java.

### Forbedringer og kommentarer
- **Kodekommentarer**: Har lagt til kommentarer for å forklare hva hver del av koden gjør.
- **Bedre struktur og lesbarhet**: Koden er strukturert for å være mer lesbar og vedlikeholdbar.
- **Feilhåndtering**: Enkel feilhåndtering er inkludert for å sikre at programmet fortsetter å kjøre selv om det oppstår feil.
- **Logging**: Loggfunksjonen skriver loggmeldinger til både konsollen og en loggfil, noe som gir enkel tilgang til resultatene.
- **README.md**: Bruksanvisningen er mer detaljert og strukturert for å veilede brukeren gjennom installasjon og kjøring av programmet.

Dette gir en fullstendig, strukturert og godt dokumentert løsning for nettverksskanning i Bash.

For å opprette en lokal webserver som tilbyr et grensesnitt for å velge ulike nettverksskanningsmetoder, se status for pågående og historiske resultater, samt vurdere kritikalitetsnivåer, kan vi bruke Flask for backend (Python) og HTML/JavaScript for frontend. Her er et grunnleggende eksempel på hvordan dette kan implementeres.

### Steg 1: Installere nødvendige pakker
Installer Flask og andre nødvendige pakker:
```bash
pip install flask flask_sqlalchemy
