AS199109: Guy Fenn-Newbury Network

About

This is a small network operated by Guy. I'm a devops engineer and IPv6 enthusiast based in High Wycombe, United Kingdom. Most network traffic will come from my homelab, and a few VLANs of my home network setup.

Why

Why manage my own network? Mainly because I find it fun. As a person working in Platform/Devops engineering, I get to play with a lot of technologies as part of my work. However, networking usually isn't one of them. So I do it as a hobby in my free time.

Additionally, IPv6 implementation in the UK is very much lacking, with many ISPs relying on CG-NAT to extend the use of IPv4 since the global exhaustion of IPv4 addresses.

Contact

Feel free to reach out via email. I'm open to advice and new opportunities.

In case things went horribly wrong, please send an email directly to noc@as199109.net. This address is monitored at least daily.

Peering

I am no longer in IXPs to peer with for the time being, as I no longer have the time to manage IXP VMs and peering relationships. However, my ASN and prefixes will be announced via the ISP Andrews and Arnold (AS20712).

Credits

I owe a lot of my knowledge to the IPv6 Discord group, who have helped guide me in setting up my ASN, getting prefix allocations, and getting IXP peering and transit set up. Without them, I would still be fumbling about with tunnelbrokers.

Additionally, this site layout was designed by ember, who created it for AS200242. They have very kindly let me use it for my site.
