Python3: Scapy attribute IP needs ip4 address as parameter, but I just have the url

I've built a webcrawler that uses the HTMLParser lib in Python. It goes on a page, and continues with the next one, linked on the loaded page, etc. It just collects the links. Now I need to protocoll the TCP/IP traffic between the hosts and my PC (packet sniffing). The result should be stored in a file.pcap. I've found an' example that seems to be useful for my purpose. Am I right?

reference code!

Here the code of the answer I'm interested in:

from scapy.all import wrpcap, Ether, IP, UDP
packet = Ether() / IP(dst="1.2.3.4") / UDP(dport=123)
wrpcap('foo.pcap', [packet])
  1. Can this code be used for it? 2. If yes, how? 3. As parameters I've just the hostnames, but not dst(ip4-address) and the dport-data. It seems clear that 1.2.3.4 and 123 are just dummies to give an example.

It appears you are very unaware of what an IP or a port mean. You should start by reading articles about that.

http://mason.gmu.edu/~afinn/html/tele/components/urls_ip.htm https://searchnetworking.techtarget.com/definition/TCP-IP

Once this is done, have a read at the documentation to start with Scapy: https://scapy.readthedocs.io/en/latest/

Also: what is your question?

I am not familiar with Scapy, but I know how to get IP by addresses, you can ping it:

$ ping stackoverflow.com
PING stackoverflow.com (151.101.193.69): 56 data bytes
64 bytes from 151.101.193.69: icmp_seq=0 ttl=46 time=374.685 ms
64 bytes from 151.101.193.69: icmp_seq=1 ttl=46 time=397.401 ms
64 bytes from 151.101.193.69: icmp_seq=2 ttl=46 time=684.908 ms
64 bytes from 151.101.193.69: icmp_seq=3 ttl=46 time=301.389 ms

then you will know that stackoverflow.com's IP is 151.101.193.69
