python-multi-DNS-to-dataframe

This code is a simple dns lookup for a sheet of ip's.

What it does

• Loads "arp_lookup.csv" (name was relative to what I was doing)
• Conducst a host name lookup on each "IP."
• Prints the host names
• Sends output to excel "output.xlsx"

Notes

• This is something I used to start programming with .
• I hope the example is a catalyst for other network guys getting into python
• I have not updated since 2018ish.
• Good adhoc function if you need to do alot of mass DNS lookups. Just wrap in lookup(df) and return data where you need it.

If you have issues and need help reach out.
