Certain URLs get redirected to a network printer...

I have a strange issue that I have yet to find a solution for.

Mostly, I don't have any problems with my network connection - it works fine on my home network and guest networks. And it was working fine on my work network, until suddenly, certain addresses started getting resolved to a printer on the LAN. We have an internal network and a guest network. I can use the guest network without any problems, but the internal network has the issue. No one else has this same issue. Most of the team runs mac, but a few others run Fedora and Ubuntu and do not experience the issue. I can also boot into Windows on the same machine and connect without any problems.

One of my coworkers can set up a wifi bridge on his mac and I can connect from that, but if someone else sets up a bridge on their mac, the issue manifests.

I have tried using different network managers (netctl, NetworkManager, systemd-networkd) as well as dhcp clients (dhcpcd, dhclient), but no change. Since I've started seeing the issue I've updated the kernel a few times. Current on 4.0.4-2-ARCH. All my other packages are up to date as well.

I would think that it's something to do with the router or the network itself, except no one else seems to have the same issue, and I have no problems on the same machine from Windows, so it makes me wonder if it's some configuration. I don't remember changing anything before this happened and I've wiped out and set up fresh network configurations along with trying the different network managers. My other thought is that it's on some kernel level and the router doesn't know how to handle the traffic correctly.

Amazon AWS, stackoverflow and lots of random addresses are affected by the issue. I'm not sure what the pattern is to what resolves correctly to the external address and what gets routed to the printer.

Re: Certain URLs get redirected to a network printer...

These sound like they are mostly in private, non-routable address space.   You are going to need to provide a lot more detail about your networks. 

What are "Certain Addresses" ?
Are you using static addresses for any machines?
What are the addresses of the machines on the networks?
On which network is the printer?
What are the subnetwork addresses for the "Internal" and "Guest"
Your friends are bridging which networks? Which network are you on?
What is your DNS configuration? How does it compare to other machines on the network(s)
Is everything bridged? Or are NATs involved?
Is there one DHCP server, or are there different DHCP servers on each net segment?
What kind of routers are involved?  Are they providing DHCP services?

Re: Certain URLs get redirected to a network printer...

Are you using static addresses for any machines?

Yes

What are the addresses of the machines on the networks?

192.168.0.0/32

On which network is the printer?

&

What are the subnetwork addresses for the "Internal" and "Guest"

Apparently these are on the same network & go to the same router. They're just separate SSIDs. So my assumption about this was incorrect.
And they are on the same subnet

Your friends are bridging which networks? Which network are you on?

They are hardwired in to the main router. If I connect with a cable, I have the same issue.

What is your DNS configuration? How does it compare to other machines on the network(s)

Primary 8.8.8.8 Secondary 8.8.4.4. These are the same DNS servers others use.

Is everything bridged? Or are NATs involved?

Everything should be bridged

Is there one DHCP server, or are there different DHCP servers on each net segment?

1 DHCP server

What kind of routers are involved?  Are they providing DHCP services?

Sonic Wall routers. The main router provides DHCP services.

EDIT:

What are "Certain Addresses" ?

I mentioned in the OP, generally any Amazon AWS service, including RDS and Redshift instances. I've had the problem with StackOverflow and random sites that I try through basically any Google search.
