Sort sets by item values

[Sergey]

I try additional sorting by tcp/udp before ip1 or addr2 like this

def sort_key(item):
    rest, eq = item.split('eq')
    protocol = item.split()[1]
    _, ip1, ip2 = rest.split('host')
    ip1 = tuple(int(i) for i in ip1.split('.'))
    ip2 = tuple(int(i) for i in ip2.split('.'))
    return int(eq), ip2, protocol, ip1

or like this

def ip_sorter(text):
    parts = text.split()
    protocol = parts[1]
    port = int(parts[-1])
    addr1 = int(ipaddress.ip_address(parts[-3]))
    addr2 = int(ipaddress.ip_address(parts[3]))
    return port, addr1, protocol, addr2

but it does not work.
What is a problem?
