Static IP block ordering mistake cost us a full Monday
Last month I set up a new office connection with a local provider in Austin and ordered a block of 8 static IPs. The sales form only asked for the count, so I assumed they'd route the subnet to our router automatically. Turns out they assign each IP to a separate device unless you specifically request a routed block. Our POS system and VoIP phones were fighting over the same address on launch day. Took three support calls and a technician visit to sort it out. Anyone else get burned by this when ordering business fiber or cable?

Ran into the same thing with a cable provider a few years back. They handed us 5 usable IPs as separate gateways on the modem, so every device grabbed its own and nothing could talk to each other on the LAN. You have to ask for a routed subnet in writing and get the tech to confirm the block shows as one CIDR, not a list of single addresses. Even then, check the subnet mask they hand you, because ours came in as a /29 when we needed the gateway inside the range.
