Counting below, you only reference 6 IP addresses on the box:
188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124,
and 126.96.36.199. What's the seventh one?

Ok. BTW, these statements indicate that you own an entire class C of
public address space. That seems unlikely, and if it's not the case,
you shouldn't be using the addresses.

Problem here. These addresses are not in the same subnet as the
primary address (188.8.131.52/24). Therefore you shouldn't use a /32
for them, you should use the actual netmask. This is definitely true
for the FIRST 63.223.71.x address, and I *think* it's true for the
others as well. I've never actually seen an example of assigning
multiple IPs for a second subnet under FreeBSD.

This is broken. You're saying "route any traffic this host is sending,
destined for itself, to an external gateway". I really doubt you want
to do that.

Again broken, for the same reasons. You don't normally enter routing
statements for your OWN IP addresses, you enter routing statements that
describe how to reach OTHER addresses/networks.
