How to Reset Your Telkom IP Address Tips, Tricks and Tutorials 15 JUL 2014

I sat with an interesting problem the other day. Essentially all of a sudden I couldn’t access this site (craiglotter.co.za) from my home connection, which of course meant that I immediately hopped on to Afrihost’s support page to log an issue (they currently host this site for me). They quickly responded saying that the site was loading just fine for them, and indeed, when accessing the site through an anonymous proxy like Anonymouse.org, I too could see that the site was up and running. So the next problem had to be my home Internet connection itself, and after running a couple of tracert requests to craiglotter.co.za, I could see that for some or other reason, one of the servers in the chain hop was simply refusing to respond to my machine’s requests.

Based on the support guy from Afrihost’s screenshot, I could see that the US-based address that was denying my traffic was allowing through his, so next on my steps to resolve was mucking about with different DNS services. Needless to say, this didn’t solve the issue either.

I rebooted the router once or twice, but that didn’t solve anything either, and then I twigged that perhaps I’m being rejected based on IP address – which in that case could be resolved by forcing a change of my Telkom line’s external IP address.

Grabbing my current external IP address via http://www.whatismyip.com/, I switched off my router for 25 minutes. No such luck. Neither did a sleep of 30 minutes do it either. Too late to call up Telkom support to request a line port reset, I located a note on the Internet that in order to manually reset your Telkom IP address in the manner least likely to raise flags (like cloning or changing your MAC address for example), you need to turn off your router for an extended time period – around 8 hours is a safe bet.

So I duly turned off the router (or rather, instructed Chantelle to turn it off before she came to bed in the evening), and the next morning as I settled in to start work, I flicked it on and checked my external IP address – success! To force a reset of your Telkom IP address, just turn off your modem for a super long period of time (+- 8 hours)!

Of course, if you are trying to do this during the day, you could just phone up Telkom and ask them to do a port reset which might solve the issue, or if you can access your router, switch the WAN connection to say the Telkom Guest Account and then back again, as this should also force an IP reassign according to Afrihost support guy (I received this last tip after having solved the issue, but it is worth mentioning here).

Anyway, problem solved!

How to Release and Renew Your IP Address via Ubuntu Terminal CodeUnit 25 APR 2011

ifconfig is the go to command when you want to view anything related to your Internet or network connections on your Linux box. To view the details of the various network adaptors currently visible, simply run:

ifconfig

This will feed you back details about your available network adapters, MAC addresses, assigned IP, etc. Note the network adapter eth0. This is the default network adapter if you are connected via normal network cable.

Do release your currently assigned IP address, simply run:

sudo ifconfig eth0 down

This will shut down the eth0 interface and subsequently releases the IP in the process. To now renew your IP, run:

sudo ifconfig eth0 up

Done. If you re-run ifconfig you’ll see the new IP address. Useful if you want to release renew your IP without rebooting the whole machine!

What is my iPhone’s current IP Address? CodeUnit 28 MAR 2011

To find out what the current IP address assigned to your iPhone is turns out to be pretty simple if you know where to look.

First, select Settings from your SpringBoard. Next, select Wi-Fi from the resulting Settings menu. This results in a list of available networks being displayed under the Choose a Network… label. To the right of each listed network is a right-arrow icon. Find the network you are currently connected to in the list (it has a tick next to it) and click on the right-arrow icon.

This will bring up the detailed network information, listing among other things the IP address your iPhone is currently assigned with from that network’s DHCP server.

Nifty.
